3.11 Watchdog Timer (Looping Detection Timer)
The purpose of the watchdog timer (WDT) is to detect the start
of CPU misoperation due to noise, etc., and bring it back to
normal.
3.11 .1 Configuration
The TMP90CM38 multiplexes the watchdog timer output
(WDTOUT) and P80. P80 (output port) is switched to the
WDTOUT pin and RESET is returned inside the chip by setting
bit WDMOD <RESCR> = “1” of the watchdog timer mode reg-
ister at address #FFD0H to “1”.
Figure 3.11 (1) shows the WDT block diagram.
