CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Clock Timer)
TMRST: Clock timer reset (2EEHD3)
This bit resets the clock timer.
When "1" is written : Clock timer reset
When "0" is written : No operation
Read-out : Always "0"
The clock timer is reset by writing "1" to TMRST. The clock timer starts immediately after this. No
operation results when "0" is written to TMRST.
This bit is write-only, and so is always "0" at read-out.
4.9.4 Programming notes
(1) The prescaler mode must be set correctly to suit the crystal oscillator to be used.
(2) When the clock timer has been reset, the interrupt factor flag (TI) may sometimes be set to "1". Conse-
quently, perform flag read-out (reset the flag) as necessary at reset.
(3) The input clock of the watchdog timer is the 2 Hz signal of the clock timer, so that the watchdog timer
may be counted up at timer reset.
(4) Read-out the interrupt factor flag (TI) only during the DI status (interrupt flag = "0"). Read-out during
EI status (interrupt flag = "1") will cause malfunction.
