Chapter 3 Port Integration Module (PIM9E128V1)
3.3.6
Port T is associated with two 4-channel timers (TIM0 and TIM1). Each pin is assigned to these modules
according to the following priority: TIM1/TIM0 > general-purpose I/O.
If the timer TIM0 is enabled, the channels configured for output compare are available on port T pins
PT[3:0]. If the timer TIM1 is enabled, the channels configured for output compare are available on port T
pins PT[7:4].
Refer to the TIM block description chapter for information on enabling and disabling the TIM module.
During reset, port T pins are configured as high-impedance inputs.
3.3.6.1
Read: Anytime. Write: Anytime.
If the associated data direction bit (DDRTx) is set to 1 (output), a read returns the value of the I/O register
bit. If the associated data direction bit (DDRTx) is set to 0 (input), a read returns the value of the pin.
3.3.6.2
Read: Anytime. Write: Never, writes to this register have no effect.
This register always reads back the status of the associated pins.
