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.
3.6.12 Port Pull-Up Pull-Down and Reduced Drive
MCU ports can be configured for internal pull-up. To reduce power
consumption and RFI, the pin output drivers can be configured to
operate at a reduced drive level. Reduced drive causes a slight increase
in transition time depending on loading and should be used only for ports
which have a light loading. Table 3-4 summarizes the port pull-up/pull-
down default status and controls.
