4-bit I/O port with latch.
When used as input port, the latch must be set to “1”.
Every bit data is possible to be set, cleared and tested by the bit manipulation
instruction of the L-register indirect addressing.
2-bit I/O port with latch.
Timer/Counter 2 external input
When used as input port, external interrupt pin, or timer/counter
external input pin, the latch must be set to “1”.
External interrupt 2 input
