TIMIOC7
Port R general purpose input/output data—Data Register
Port R pins 7 through 0 are associated with TIM channels TIMIOC7 through TIMIOC0.
When not used with the alternative function, these pins can be used as general purpose I/O.
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the
buffered pin input state is read.
Port R input data—
This register always reads back the buffered state of the associated pins. This can also be used to detect overload
or short circuit conditions on output pins.
