6.4.1 Port B Data Register
Technical Data
Address:
The outputs for the upper four bits of port A (PA4–PA7) can drive
light-emitting diodes (LEDs). PA4–PA7 can sink approximately 10 mA of
current to V
If the PIRQ bit in the mask option register is programmed to logic 1,
PA0–PA3 pins function as external interrupt pins. See
External Interrupt Module
Port B is a 6-bit bidirectional port.
The port B data register (PORTB) contains a latch for each port B pin.
PB[5:0] — Port B Data Bits
Reset:
Read:
Write:
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.
