FIXED-POINT DIGITAL SIGNAL PROCESSOR
SPRS462B – SEPTEMBER 2007 – REVISED JANUARY 2008
The timers can be used to: time events, count events, generate pulses, interrupt the CPU, and send
synchronization events to the EDMA3 channel controller.
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.
