Section 9 I/O Ports
9.1.2
DR is an 8-bit readable/writable register that stores the output data of the pins to be used as the
general output port.
The initial value of DR is H'00.
9.1.3
PORT is an 8-bit read-only register that reflects the port pin state. A write to PORT is invalid.
When PORT is read, the DR bits that correspond to the respective DDR bits set to 1 are read and
the status of each pin whose corresponding DDR bit is cleared to 0 is also read regardless of the
ICR value.
The initial value of PORT is undefined and is determined based on the port pin state.
