DS1682 Alarm clock chip, can put the ENVET pin is pulled, he could accumulate count 1/4 seconds, so I didn't add crystals (refer to the manual officer chip document), write a ban and RAM write didn't open, but it won't register is written in, not only the config registers, write banning register write is not enough, so I can only be written into the accumulator and RAM Alarm and time, other are written, all very meng, hope someone useful to show just a little, be obliged,

Increase the timing counter?

CodePudding user response:

Added, the timer count I can read can write, is can't change other register, write banned I didn't write, because I don't write in, only read 0 x00
