FUNCTION DESCRIPTION
Port 1.7 GPIO
8051 P1.7 GPIO.
PINT0.1
This pin also can be configured as the expanded INT0 interrupt.
T0 Timer 0 Input
This pin also can be configured as Timer 0 input.
SWB0
P1.7
I/O, A
17
This pin also serves as one of the connection for analog switch B. The control of the
analog switch is done by setting of ANEN of IOCFGP1.7.
Port 1.6 GPIO
8051 P1.6 GPIO.
PINT0.0
This pin also can be configured as the expanded INT0 interrupt.
T1 Timer 1 Input
This pin also can be configured as Timer 1 input.
SWB1
P1.6
I/O, A
18
This pin also serves as one of the connection for analog switch B. The control of the
analog switch is done by setting of ANEN of IOCFGP1.6.
Port 1.5 GPIO
8051 P1.5 GPIO.
SWC3
P1.5
I/O, A
19
This pin also serves as one of the connection for analog switch B. The control of the
analog switch is done by setting of ANEN of IOCFGP1.5.
Port 1.4 GPIO
8051 P1.4 GPIO.
SWC2
P1.4
I/O, A
20
This pin also serves as one of the connection for analog switch B. The control of the
analog switch is done by setting of ANEN of IOCFGP1.4.
Port 1.3 GPIO
8051 P1.3 GPIO.
SCL
This pin also can be configured as the SCL signal of the I2C master or I2C slave
controller. In I2C master mode, this pin should be configured as open-drain output. In
I2C slave, this pin should be configured as input only.
SWC1
P1.3
I/O, A
21
This pin also serves as one of the connection for analog switch B. The control of the
analog switch is done by setting of ANEN of IOCFGP1.3.
Port 1.2 GPIO
8051 P1.2 GPIO.
SDA
This pin also can be configured as the SDA signal of the I2C master or I2C slave
controller. In this operation mode, this pin should also be configured as bi-directional
I/O with open-drain output.
SWC0
P1.2
I/O, A
22
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 IOCFGP1.2.
