Port H general purpose input/output data—Data Register
Port H pin 1 is associated with the TXD signal of the SCI6 module and the MOSI signal of the routed SPI1.
The routed SPI1 function takes precedence over the SCI6 and the general purpose I/O function if the routed SPI1
module is enabled. The SCI6 function takes precedence over the general purpose I/O function if the SCI6 is enabled.
When not used with the alternative function, this pin 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 H general purpose input/output data—Data Register
Port H pin 0 is associated with the RXD signal of the SCI6 module and the MISO signal of the routed SPI1.
The routed SPI1 function takes precedence over the SCI6 and the general purpose I/O function if the routed SPI1
module is enabled. The SCI6 function takes precedence over the general purpose I/O function if the SCI6 is enabled.
When not used with the alternative function, this pin 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 H 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.
