Multiplexed pin whose function is selected by the T2
bit of the PORTBFCG register. If T2=0, the pin is the
bi-directional I/O port bit PB0. If T2=1, the pin is the
active-high T2 signal from 8051 Timer2, which pro-
vides the input to Timer2 when C/T2=1. When
C/T2=0, Timer2 does not use this pin.
Multiplexed pin whose function is selected by the
T2EX bit of the PORTBCFG register. If T2EX=0, the
pin is the bi-directional I/O port bit PB1. If T2EX=1,
the pin is the active-high T2EX signal from 8051
Timer2.
Multiplexed pin whose function is selected by the
RXD1 bit of the PORTBCFG register. If RXD1=0,
the pin is the bi-directional I/O port bit PB2. If
RXD1=1, the pin is the active-high RXD1 input sig-
nal for 8051 UART1, which provides data to the
UART in all modes.
Multiplexed pin whose function is selected by the
TXD1 bit of the PORTBCFG register. If TXD1=0, the
pin is the bi-directional I/O port bit PB3. If TXD1=1,
the pin is the active-high TXD1 output pin for 8051
UART1 which provides the output clock in sync
mode and the output data in async mode.
Multiplexed pin whose function is selected by the
INT4 bit of the PORTBCFG register. If INT4=0, the
pin is the bi-directional I/O port bit PB4. If INT4=1,
the pin is the 8051 INT4 interrupt request signal.
The INT4 pin is edge-sensitive, active high.
Multiplexed pin whose function is selected by the
INT5 bit of the PORTBCFG register. If INT5=0, the
pin is the bi-directional I/O port bit PB5. If INT5=1,
the pin is the INT5# interrupt register signal. The
INT5# pin is edge-sensitive, active low.
Multiplexed pin whose function is selected by the
INT6 bit of the PORTBCFG register. If INT6=0, the
pin is the bi-directional I/O port bit PB6. If INT6=1,
the pin is the INT6 interrupt request signal. The
INT6 pin is edge-sensitive, active high.
