TMRST: Clock timer reset (0F4H•D3)
This bit resets the clock timer.
When 1 is written: Clock timer reset
When 0 is written: No operation
Reading: Always 0
The clock timer is reset by writing 1 to TMRST. The clock timer starts immediately after this. No opera-
tion results when 0 is written to TMRST.
This bit is write-only, and so is always 0 when read.

4.6.5 Programming notes

(1) Note that the frequencies and times differ from the description in this section when the oscillation
frequency is not 32.768 kHz.
(2) Reading of interrupt factor flags is available at EI, but be careful in the following cases.
If the interrupt mask register value corresponding to the interrupt factor flag to be read is set to 1, an
interrupt request will be generated by the interrupt factor flag set timing, or an interrupt request will
not be generated. Be very careful when interrupt factor flags are in the same address.
