Preliminary Technical Data
PORT 0
Port 0 is controlled directly through the bit-addressable Port 0
SFR (P0, 0x80). The weak internal pull-ups for Port 0 are
configured through the Port 0 Weak Pull-Up Enable SFR
(PINMAP0, 0xB2); they are enabled by default. The weak
internal pull-up is disabled by writing a 1 to PINMAP0.x.
Port 0 pins also have various secondary functions as described
in Table 153. The alternate functions of Port 0 pins can be
activated only if the corresponding bit latch in the Port 0 SFR
contains a 1. Otherwise, the port pin remains at 0.
PORT 1
Port 1 is an 8-bit bidirectional port controlled directly through
the bit-addressable Port 1 SFR (P1, 0x90). The weak internal
pull-ups for Port 1 are configured through the Port 1 Weak
Pull-Up Enable SFR (PINMAP1, 0xB3); they are enabled by
default. The weak internal pull-up is disabled by writing a 1 to
PINMAP1.x.

Port 1 pins also have various secondary functions as described
in Table 154. The alternate functions of Port 1 pins can be
activated only if the corresponding bit latch in the Port 1 SFR
contains a 1. Otherwise, the port pin remains at 0.
PORT 2
Port 2 is a 4-bit bidirectional port controlled directly through
the bit-addressable Port 2 SFR (P2, 0xA0). Note that P2.3 can be
used as an output only. The weak internal pull-ups for Port 2 are
configured through the Port 2 Weak Pull-Up Enable SFR
(PINMAP2, 0xB4); they are enabled by default. The weak
internal pull-up is disabled by writing a 1 to PINMAP2.x.
Port 2 pins also have various secondary functions as described
in Table 155. The alternate functions of Port 2 pins can be
activated only if the corresponding bit latch in the Port 2 SFR
contains a 1. Otherwise, the port pin remains at 0.
