6.9. Timers
The S5N8947 has two 32-bit timers. These timers can operate in interval mode or in toggle mode.
The output signals are TOUT0 and TOUT1, respectively.
You enable or disable the timers by setting control bits in the timer mode register, TMOD. An
interrupt request is generated whenever a timer count-out (down count) occurs.
Watchdog timer is also implemented in the S5N8947. The following guidelines apply to watchdog
timer functions:
—
When a watchdog timer is enabled, it loads a data value to its count register and begins decrementing
the count register value by the system clock.
—
If the reset from the watchdog timer (WDRESET) reaches to zero, the Watchdog will start its reset
sequence. The reset value is then reloaded and the watchdog timer is disabled.
—
The WDRESET performs the same function as the External Reset (System Reset) to each block.
