7.2.4 Port LED Drive Capability
All outputs can drive light-emitting diodes (LEDs). These pins can sink approximately 10 mA of current to
VSS.
7.2.5 Port A I/O Pin Interrupts
If the PIRQ bit in the mask option register is programmed to logic 1, PA0–PA3 pins function as external
7.3 Port B
Port B is a 2-bit bidirectional port.
7.3.1 Port B Data Register
The port B data register contains a latch for each port B pin.
PB[3:2] — Port B Data Bits
These read/write bits are software programmable. Data direction of each port B pin is under the control
of the corresponding bit in data direction register B. Reset has no effect on port B data.
NOTE
PB4–PB5 and PB0–PB1 should be configured as inputs at all times. These
bits are available for read/write but are not available externally. Configuring
them as inputs will ensure that the pulldown devices are enabled, thus
properly terminating them.

Note:
PB5, PB4, PB1, and PB0 should be configured as inputs at all times. These bits are avail-
able for read/write but are not available externally. Configuring them as inputs will ensure
that the pulldown devices are enabled, thus properly terminating them.
