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. For PE2, signal direction is
controlled through the SCI PRR. The signal can be configured as an SCI
signal SCLK through the SCI PCR.
This input is 5 V tolerant.
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.
