CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Clock Timer)
Table 4.7.1 shows the clock timer control bits and their
addresses.

Table 4.7.1 Control bits of clock timer
Timer data (0E3H)
The l6 Hz to 2 Hz timer data of the clock timer can be read
from this register. These four bits are read-only, and write
operations are invalid.
After an initial reset, the timer data is initialized to "0H".
Interrupt mask registers (0EBH D0–D2)
These registers are used to mask the clock timer interrupt.
When "1" is written:
Enabled
When "0" is written:
Masked
Reading:
Valid
The interrupt mask register bits (EIT32, EIT8, EIT2) mask
the corresponding interrupt frequencies (32 Hz, 8 Hz, 2 Hz).
After an initial reset, these registers are all set to "0".
