FUNCTION DESCRIPTION
Port 3.1 GPIO
8051 P3.1 GPIO.
CEX3 PCA CCAP Module 3
This pin also can be configured as CEX pin for PCA CCP module 3. CEX is an I/O
interface signal for compare/capture input and PWM output.
SWA2
This pin also serves as one of the connection for analog switch A. The control of the
analog switch is done by setting of ANEN of IOCFGP3.1.
