1.10 Timers
The DSP56321 has three identical and independent timers. Each timer can use internal or external clocking and can
either interrupt the DSP56321 after a specified number of events (clocks) or signal an external device after
counting a specific number of internal events.

In the Stop state, the signal maintains the last state as follows:
• If the last state is input, the signal is an ignored input.
• If the last state is output, these lines have weak keepers that maintain the last output state even if the drivers are tri-stated.
The Wait processing state does not affect the signal state.

Serial Clock—Provides the input or output clock used by the transmitter and/or
the receiver.
Port E 2—The default configuration following reset is GPIO input PE2. When
configured as PE2, signal direction is controlled through the Port E Direction
Register. The signal can be configured as an SCI signal SCLK through the Port
E Control Register.
Timer 0 Schmitt-Trigger Input/Output— When Timer 0 functions as an
external event counter or in measurement mode, TIO0 is used as input. When
Timer 0 functions in watchdog, timer, or pulse modulation mode, TIO0 is used
as output.
The default mode after reset is GPIO input. TIO0 can be changed to output or
configured as a timer I/O through the Timer 0 Control/Status Register (TCSR0).
Timer 1 Schmitt-Trigger Input/Output— When Timer 1 functions as an
external event counter or in measurement mode, TIO1 is used as input. When
Timer 1 functions in watchdog, timer, or pulse modulation mode, TIO1 is used
as output.
The default mode after reset is GPIO input. TIO1 can be changed to output or
configured as a timer I/O through the Timer 1 Control/Status Register (TCSR1).
Timer 2 Schmitt-Trigger Input/Output— When Timer 2 functions as an
external event counter or in measurement mode, TIO2 is used as input. When
Timer 2 functions in watchdog, timer, or pulse modulation mode, TIO2 is used
as output.
The default mode after reset is GPIO input. TIO2 can be changed to output or
configured as a timer I/O through the Timer 2 Control/Status Register (TCSR2).
