Setting the RDPT bit in the TMSK2 register configures all port T outputs
to have reduced drive levels. Levels are at normal drive capability after
reset. The TMSK2 register can be read or written anytime after reset
Refer to Enhanced Capture Timer.

Description
Port A and port B pins are used for address and data in
expanded 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 1 and general-purpose I/O.
Analog-to-digital converter 0 and general-purpose I/O.
General purpose I/O. PCAN[1:0] are used with the
MSCAN12 module and cannot be used as 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 used with the pulse-width
modulator when enabled.
Serial communications interfaces 1 and 0 and serial
peripheral interface 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
subsystem.
1. In 80-pin QFP package only TxCAN and RxCAN are available. PortCAN[2:7] pins should either be defined as outputs or
have their pull-ups enabled.
