12.6.11 Day-Of-Week Register (DOWR)
12.6.12 Chronograph Data Register (CHRR)

Address:
Address:
This read/write register contains the current value of the day-of-week
counter. This register can be read at any time without affecting the
counter count. Writing to this register loads the value to the day-of-week
counter and the counter continues to count from this new value.
The day-of-week counter value rolls over to 0 ($00) after reaching 6
($06). Writing a value other than 0 to 6 to this register has no effect.
This read-only chronograph data register contains the value in the
chronograph counter. Reset clears the chronograph data register.
Setting the chronograph counter reset bit (CHRCLR) also clears the
chronograph data register.
The chronograph data register has a resolution of 1/100 seconds
(10ms). The chronograph counter value rolls over to $00 after reaching
$63.
