Port K Data Direction—
This bit determines whether the associated pin is an input or output.
1 Associated pin configured as output
0 Associated pin configured as input
Port T general purpose input/output data—Data Register, TIM output, routed PWM 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.
