Switching between Input and Output of Bitwise I/O Port
A bitwise I/O port is a port whose four bits are individually assigned inputs or output. The
μ
PD17207 supports
only one bitwise I/O port: P0D. The bitwise input/output selection is performed by the following I/O control register.
When the bits of this port are assigned from inputs to outputs, output latches of P0A, P0B, P0C, P0D, and P1A are
output to the corresponding ports.
