173 / 191 page  TMS320DM647 TMS320DM648 www.ti.com SPRS372H – MAY 2007 – REVISED APRIL 2012 6.21 Timers The device has four 64-bit general-purpose timers of which only Timer 0 and Timer 1 have external input/output. The timers can be used to: time events, count events, generate pulses, interrupt the CPU, and send synchronization events to the EDMA3 channel controller. 6.21.1 General-Purpose Timers 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). 6.21.2 Timer Peripheral Register Descriptions Table 6-85.
