Overview Once you have reserved a block of registers for the time-of-day clock, you have to
set the correct time. With Concept, you must go online and set the register bits
individually, using the following guidelines for setting the status bits and setting the
time bits. The CPU must be running.
Setting the
Status Bits
The control register (4x) uses its four most significant bits to report status.
