7.15.1 Timers Device-Specific Information

The C6455 device has two general-purpose timers, Timer0 and Timer1, each of which can be configured as a general-purpose timer or a watchdog timer. When configured as a general-purpose timer, each timer can be programmed as a 64 bit timer or as two separate 32 bit timers.

Each timer is made up of two 32 bit counters: a high counter and a low counter. The timer pins, TINPLx and TOUTLx are connected to the low counter. The high counter does not have any external device pins.
