P3.7-0
Bits 7-0
Purpose I/O Port 3. This register functions as a general purpose I/O port. In
addition, all the pins have an alternative function listed below. Each of the
functions is controlled by several other SFRs. The associated Port 1 latch bit
must contain a logic one before the pin can be used in its alternate function
capacity.
RD
Bit 7
External Data Memory Read Strobe. This pin provides an active low read
strobe to an external memory device.
WR
Bit 6
External Data Memory Write Strobe. This pin provides an active low write
strobe to an external memory device.
T1
Bit 5
Timer/Counter External Input. A 1 to 0 transition on this pin will increment
Timer 1.
T0
Bit 4
Counter External Input. A 1 to 0 transition on this pin will increment Timer 0.
INT1
Bit 3
External Interrupt 1.
A falling edge/low level on this pin will cause an
external interrupt 1 if enabled.
INT0
Bit 2
External Interrupt 0.
A falling edge/low level on this pin will cause an
external interrupt 0 if enabled.
TXD0
Bit 1
Serial Port 0 Transmit. This pin transmits the serial port 0 data in serial port
modes 1, 2, 3 and emits the synchronizing clock in serial port mode 0.
RXD0
Bit 0
Serial Port 0 Receive. This pin receives the serial port 0 data in serial port
modes 1, 2, 3 and is a bi-directional data transfer pin in serial port mode 0.
