6.6 Watch Timer
The
μ
PD753108 has one watch timer channel which has the following functions.
Sets the test flag (IRQW) at 0.5-second intervals. The standby mode can be released by the IRQW.
0.5-second interval can be created by both the main system clock (4.194304 MHz) and subsystem clock
(32.768 kHz).
Convenient for program debugging and checking as interval becomes 128 times longer (3.91 ms) with the
fast feed mode.
Outputs the frequencies (2.048, 4.096, 32.768 kHz) to the P23/BUZ pin, usable for buzzer and trimming of
system clock oscillation frequencies.
Clears the frequency divider to make the watch start with zero seconds.
