Port H general purpose input/output data—Data Register
Port H pin 7 is associated with the TXD signal of the SCI5 module and the SS signal of the routed SPI2.
The routed SPI2 function takes precedence over the SCI5 and the general purpose I/O function if the routed SPI2
module is enabled. The SCI5 function takes precedence over the general purpose I/O function if the SCI5 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 6 is associated with the RXD signal of the SCI5 module and the SCK signal of the routed SPI2.
The routed SPI2 function takes precedence over the SCI5 and the general purpose I/O function if the routed SPI2
module is enabled. The SCI5 function takes precedence over the general purpose I/O function if the SCI5 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 5 is associated with the TXD signal of the SCI4 module and the MOSI signal of the routed SPI2.
The routed SPI2 function takes precedence over the SCI4 and the general purpose I/O function if the routed SPI2
module is enabled. The SCI4 function takes precedence over the general purpose I/O function if the SCI4 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 4 is associated with the RXD signal of the SCI4 module and the MISO signal of the routed SPI2.
The routed SPI2 function takes precedence over the SCI4 and the general purpose I/O function if the routed SPI2
module is enabled. The SCI4 function takes precedence over the general purpose I/O function if the SCI4 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 3 is associated with the TXD signal of the SCI7 module and the SS signal of the routed SPI1.
The routed SPI1 function takes precedence over the SCI7 and the general purpose I/O function if the routed SPI1
module is enabled. The SCI7 function takes precedence over the general purpose I/O function if the SCI7 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 2 is associated with the RXD signal of the SCI7 module and the SCK signal of the routed SPI1.
The routed SPI1 function takes precedence over the SCI7 and the general purpose I/O function if the routed SPI1
module is enabled. The SCI7 function takes precedence over the general purpose I/O function if the SCI7 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.
