7.15 Timers

The timers can be used to: time events, count events, generate pulses, interrupt the CPU, and send

synchronization event so the EDMA3 channel controller.

7.15.1 Timers Device-Specific Information

The device has six general purpose timers: Timer0 to Timer5, 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 pinout is

described in the next section.

7.15.1.1 Timer I/O Selection

Not all timer inputs and outputs are pinned out of the device. The six timers have a flexible (e.g. software

controlled) selection of timer inputs and outputs. At the chip level there are four timer pins, two input pins

(TIMI[1:0]) and two output pins (TIMO[1:0]). Each timer input can be configured to be driven by either of

the timer input pins, or by an FSYNC event (FSEVT[3:2]). Each output pin can be driven by any of the

timer outputs. This is programmable through software via the Timer Pin Manager Block, as shown in the

Figure 7-38. Not shown in the figure is the logic that gates the timer resets that are routed to the PLL

controller, shown in Figure 7-39.
