*The first entry in column ACCESS is valid between missions. The second entry shows the applicable
access mode while a mission is in progress.
**While a mission is in progress, these addresses can be read. The first attempt to write to these registers
(even read-only ones), however, will end the mission and overwrite selected writeable registers.
TIMEKEEPING
The RTC/alarm and calendar information is accessed by reading/writing the appropriate bytes in the
register page, address 200h to 206h. Note that some bits are set to 0. These bits will always read 0
regardless of how they are written. The contents of the time, calendar, and alarm registers are in the
Binary-Coded Decimal (BCD) format.
