Description
7-6, 3-1
PTT
Port T general purpose input/output data—Data Register, TIM output
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
The TIM output function takes precedence over the general purpose I/O function if the related channel is enabled.

PTT
Port T general purpose input/output data—Data Register, TIM output, routed PWM output, API_EXTCLK output
When not used with the alternative function, the associated pin can be used as general purpose I/O. In general
purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
The TIM output function takes precedence over the routed PWM, API_EXTCLK function and the general purpose
I/O function if the related channel is enabled.
The routed PWM function takes precedence over API_EXTCLK and the general purpose I/O function if the related
channel is enabled.
The API_EXTCLK takes precedence over the general purpose I/O function if enabled.
