The first entry in column ACCESS TYPE is valid between missions. The second entry shows the applicable
access type while a mission is in progress.
TIMEKEEPING AND CALENDAR
The RTC/alarm and calendar information is accessed by reading/writing the appropriate bytes in the register page,
address 200h to 205h. For readings to be valid, all RTC registers must be read sequentially starting at address
0200h. Some of the RTC bits are set to 0. These bits always read 0 regardless of how they are written. The
number representation of the RTC registers is BCD format (binary-coded decimal).

The RTC of the DS2422 can run in either 12-hour or 24-hour mode. Bit 6 of the Hours Register (address 202h) is
defined as the 12- or 24-hour mode select bit. When high, the 12-hour mode is selected. In the 12-hour mode, bit 5
is the AM/PM bit with logic 1 being PM. In the 24-hour mode, bit 5 is the 20-hour bit (20 to 23 hours). The CENT bit,
bit 7 of the Months Register, can be written by the user. This bit changes its state when the years counter
transitions from 99 to 00.
The calendar logic is designed to automatically compensate for leap years. For every year value that is either 00 or
a multiple of 4 the device adds a 29
th
of February. This works correctly up to (but not including) the year 2100.
