FUNCTION DESCRIPTION
Port 4.5 GPIO
8051 P4.5 GPIO.
SWC5
P4.5
I/O, A
-
This pin also serves as one of the connection for analog switch C. The control of the
analog switch is done by setting of ANEN of IOCFGP4.5.
Port 1.1 GPIO
8051 P1.1 GPIO.
CEX1 PCA CCAP Module 1
This pin also can be configured as CEX pin for PCA CCP module 1. CEX is an I/O
interface signal for compare/capture input and PWM output.
ADD4
P1.1
I/O, A
23
This pin also can be configured as the input to the ADC channel D by setting ANEN of
IOCFGP1.1 to 1. Only one of ADD1, ADD2, ADD3 and ADD4 can be enabled at any
one time.
Port 1.0 GPIO
8051 P1.0 GPIO.
CEX0 PCA CCAP Module 0
This pin also can be configured as CEX pin for PCA CCP module 0. CEX is an I/O
interface signal for compare/capture input and PWM output.
ADD3
P1.0
I/O, A
24
This pin also can be configured as the input to the ADC channel D by setting ANEN of
IOCFGP1.0 to 1. Only one of ADD1, ADD2, ADD3 and ADD4 can be enabled at any
one time.
Port 0.7 GPIO
8051 P0.7 GPIO.
RXD0
This pin also can be configured as RXD of UART 0.
ADD2
P0.7
I/O, A
25
This pin also can be configured as the input to the ADC channel D by setting ANEN of
IOCFGP0.7 to 1. Only one of ADD1, ADD2, ADD3 and ADD4 can be enabled at any
one time.
Port 0.6 GPIO
8051 P0.6 GPIO.
TXD0
This pin also can be configured as TXD of UART 0.
ADD1
P0.6
I/O, A
26
This pin also can be configured as the input to the ADC channel D by setting ANEN of
IOCFGP0.6 to 1. Only one of ADD1, ADD2, ADD3 and ADD4 can be enabled at any
one time.
Port 0.5 GPIO
8051 P0.5 GPIO.
PINT1.5
This pin also can be configured as the expanded INT1 interrupt.
ADC2
P0.5
I/O, A
27
This pin also can be configured as the input to the ADC channel C by setting ANEN of
IOCFGP0.5 to 1. Only one of ADC1 and ADC2 can be enabled at any one time.
