Hello, Sergei! Monday November 19, 2001 22:00:26 Aleksandr Majorov -> Sergei Chikalev: AM>>> What a fool! AM>>> I said it in Russian - RTFM! AM>>> Read the documents - they rule! ;) SC>> ... And where can I get them? Maybe you have it?? AM> Yes. Some kind of news. Tama the watch was described AM> and all registers are bit-mapped. And here is a clipping from that newspaper: ╔═───────────────════ ════───────────────═╗ │ CMOS clock │ ╚═─────────────────── ───────────────────═╝ Alexander Mayorov Dmitry Lomov In this issue we decided to tell you about such a wonderful things like the CMOS clock chip. What kind of animal is this and for what does it need, you ask? But look for yourself! This chip provides computer-independent sub- even time, generation of interrupt signals from the alarm clock, and so on can also be used as a small non-volatile RAM on 50 bytes. A special feature of CMOS watches is their extremely low energy consumption! (according to the reference book, the current consumption is from 0.1 to 4 mA!). If you connect a backup power source to this chip,information, then counting time and storing information in the internal RAM will be guaranteed even when the computer is turned off. You may ask - well, why do I need this? Indeed, under normal conditions, a computer clock does not very much needed. But! If you write letters to Ehi from time to time, then the data a watch will save you from having to constantly look at the calendar Give and wall clock to put the time/date. Well, for BBS or "miler" watches are very, very necessary! Actually, the need for a watch was one of the reasons for the creation giving a new version of the BBS. Which may be discussed next current issues of Newski. Well, now let's get down to business! The microcircuit is called 512VI1, its proprietary prototype is MS 146818, as well as the largest rulez - DALLAS 1287, which has internal quartz and a battery for 10 years. It should be said that such microcircuits are found in PCs 286 and 386, and therefore available thanks to the great Upgrade... To begin with, pin assignments: 01 NC not used 02 OSC1 generator input 03 OSC2 generator output 04 AD0\n 05 AD1\n 06 AD2\n 07 AD3 multiplex bus 08 AD4 address/data 09AD5/ 10AD6/ 11AD7/ 12 GND ground 13 /CE crystal selection 14 AS address strobe 15 R/W read/write16 NC not used 17 /DS data strobe 18 /RES reset input 19 /IRQ interrupt request output 20 SED frequency control CKOUT 21 CKOUT clock output 22 PS supply voltage failure monitoring 23 SQW output of software-controlled frequency divider 24 +Ucc +3...+5 volts And now in more detail: Pin 02 (OSC1) must be supplied with a frequency from an external generator speaker, or connect a quartz relay to pins 02/03 (OSC1/OSC2) zonator Pins 4...11 (AD0...AD7) - address/data bus, connected to processor data bus. Pin 13 (/CE) - crystal selection. If there is a log. "1" for given The microcircuit is blocked at the current input. There is one feature: at this input there must be a state Log "0" during the entire cycle of accessing the chip. Those. simultaneously with (or before) selecting the register address at the /CE input log "0" should be set and its state should not change during the entire cycle of accessing the selected register! It is most convenient and simple to set the state at this input log."0" for the entire time the computer is running. The register number is selected by feeding it to the AD-bus RES/DATA (AD0...AD7) and applying log "1" to input 14 (AS) Pins are used to read/write data to/from register(s) 15 (R/W) - selection of read/write mode (log. "1" and"0") and 17 (DS) - data strobe. When applying log "0" to the R/W output, data is written to previously selected register, and when applying log "0" to the DS pin - read Retrieving data from the register. The appearance of log "0" on pin 19 (/IRQ) reports the system process dark interrupt LSI. In all other cases, the data output is in the third logical state (high impedance). Supplying log "0" to the 22nd pin (/PS) informs the LSI that There was a supply voltage failure and the contents of the registers were incomplete. sure. If there is a backup power source, then this input submit log. "1". At pin 23 (SQW) there are frequency pulses that receive - is determined by dividing the frequency of the clock generator by a coefficient specified programmed. At output 21 (CKOUT) there are pulses, the frequency of which depends from the state of input 20 (SED). If there is log "1" frequency at The SQW output coincides with the generator frequency (OSC1-OSC2). When on- If log "0" is present at the SED input, the frequency at the SQW output is four times less than the generator frequency (OSC1-OSC2). The chip has 64 eight-bit registers. When working with they must first indicate which register to work with (write its number in the address register), and then write/read tion.

If a number in the interval #C0...#FF is written into registers #00...#09 - it is a state of indifference. Those. if alarm clock = #FF, then it will fire every hour. BEEPING A SOUND SIGNALWHEN THE ALARM GOES GOING ───────────────────────────── It is necessary to set AIE=SQWE=1 UIE=PIE=0 in the {B} register. The audio frequency at the SQW output is set by the RS bits of the {A} register. When the alarm goes off, the IRQ output will be set to log. "0". Those. to generate sound you need to OR the SQW outputs and IRQ You can install an RC chain, which after some time after setting IRQ to #0, a reset signal will be generated, and the sound will stop.
