Port A and port B pins are used for address and data in ex-
panded modes. The port data registers are not in the address
map during expanded and peripheral mode operation. When
in the map, port A and port B can be read or written any time.
DDRA and DDRB are not in the address map in expanded or
peripheral modes.
Analog-to-digital converter and general-purpose I/O.
Byte Data Link Communication (BDLC) subsystem and
general-purpose I/O.
Mode selection, bus control signals and interrupt service
request signals; or general-purpose I/O.
General-purpose I/O. PP[3:0] are use with the pulse-width
modulator when enabled.
Serial communications interface and serial peripheral in-
terface subsystems and general-purpose I/O.
General-purpose I/O when not enabled for input capture and
output compare in the timer and pulse accumulator sub-
system.
