Reading the Time-of-Day Clock
Overview
This section uses an example to describe how to interpret the time-of-day clock
registers.
Example
If you reserved registers 400100...400107 as your TOD clock registers, set the time
bits, and then read the clock at 9:25:30 on Thursday, July 16, 1998, the registers
would display the following values:
