The timers can be used to: time events, count events, generate pulses, interrupt the CPU, and send synchronization events to the EDMA3 channel controller. Each of the general-purpose timers 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. For more detailed information, see the TMS320DM647DM648 DSP 64-Bit Timer User's Guide (literature number SPRUEL0). Table 6-84.
