This is also the least significant byte (LSB) of
the 16-bit wide system bus in Microprocessor
mode or Extended Microcontroller mode. In
multiplexed system bus configuration, these
pins are address output as well as data input or
output.

Legend: I = Input only; O = Output only; I/O = Input/Output;
P = Power; — = Not Used;
TTL = TTL input;
ST = Schmitt Trigger input
Note 1: The output is only available by the peripheral operation.
2: Open drain input/output pin. Pin forced to input upon any device RESET.
