7.1
Port 4 Pin-Out Selection Register
Bits 5,4,3, and 2 control the configuration of multiplexed pins 20, 19, 18, and
17. If a bit is set to 0, the pin functions as a PWM output port. If a bit is set to 1, the
pin functions as a programmable regular input/output port. See Table 42. This
value is the default following a Power-On Reset.
