Port H general purpose input/output data—Data Register, LCD segment driver output
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, LCD segment driver output, SS of SPI, SDA of IIC
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, LCD segment driver output, SCK of SPI, ECLK
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, LCD segment driver output, MOSI of SPI
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, LCD segment driver output, MISO of SPI, SCL of IIC
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.
• The LCD segment driver output function takes precedence over the general purpose I/O function if enabled
• The LCD segment driver output takes precedence over the SPI, IIC and the general purpose I/O function
• The SDA of IIC takes precedence over the SPI and the general purpose I/O function
• The SS of SPI takes precedence over the general purpose I/O function
• The LCD segment driver output takes precedence over the SPI, ECLK and the general purpose I/O function
• The SCK of SPI takes precedence over the ECLK and the general purpose I/O function
• The ECLK takes precedence over the general purpose I/O function
• The LCD segment driver output takes precedence over the SPI and the general purpose I/O function
• The MOSI of SPI takes precedence over the general purpose I/O function
• The LCD segment driver output takes precedence over the SPI, IIC and the general purpose I/O function
• The SCL of IIC takes precedence over the SPI and the general purpose I/O function
• The MISO of SPI takes precedence over the general purpose I/O function
