2.11 Timers
The DSP56309 has three identical and independent timers. Each can use internal or external
clocking, interrupt the DSP56309 after a specified number of events (clocks), or signal an
external device after counting a specific number of internal events.

The Wait processing state does not affect the signal state.
Type
If the last state is input, the signal is an ignored input.
If the last state is output, these lines are tri-stated.

Timer 0 Schmitt-Trigger Input/Output
As an external event counter or in Measurement mode, TIO0 is input. In
Watchdog, Timer, or Pulse Modulation mode, TIO0 is output. The default
mode after reset is GPIO input. This can be changed to output or
configured as a Timer Input/Output through the Timer 0 Control/Status
Register (TCSR0). This input is 5 V tolerant.
Timer 1 Schmitt-Trigger Input/Output
As an external event counter or in Measurement mode, TIO1 is input. In
Watchdog, Timer, or Pulse Modulation mode, TIO1 is output. The default
mode after reset is GPIO input. This can be changed to output or
configured as a Timer Input/Output through the Timer 1 Control/Status
Register (TCSR1). This input is 5 V tolerant.
Timer 2 Schmitt-Trigger Input/Output
As an external event counter or in Measurement mode, TIO2 is input. In
Watchdog, Timer, or Pulse Modulation mode, TIO2 is output. The default
mode after reset is GPIO input. This can be changed to output or
configured as a Timer Input/Output through the Timer 2 Control/Status
Register (TCSR2). This input is 5 V tolerant.
