Port A general purpose input/output data—Data Register, LCD segment driver output
The associated pin can be used as general purpose I/O when not used as alternative function is not enabled. 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.
Port A general purpose input/output data—Data Register, LCD segment driver output, API_EXTCLK
The associated pin can be used as general purpose I/O when not used as alternative function. 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.
Port A general purpose input/output data—Data Register, LCD segment driver output, XIRQ
The associated pin can be used as general purpose I/O when not used as alternative function. 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.
Port A general purpose input/output data—Data Register, LCD segment driver output, IRQ
The associated pin can be used as general purpose I/O when not used as alternative function. 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.
