General-Purpose I/O Port 1. This register functions as a general-purpose I/O port. In addition, all the pins have an
bits 70
alternative function listed below. Each of the functions is controlled by several other SFRs. The associated Port 1
latch bit must contain a logic ‘1’ before the pin can be used in its alternate function capacity. To use the alternate
function, set the appropriate mode in P1DDRL (SFR AEh), P1DDRH (SFR AFh).
INT5/SCK
External Interrupt 5. A falling edge on this pin will cause an external interrupt 5 if enabled.
bit 7
SPI Clock. The master clock for SPI data transfers.
INT4/MISO
External Interrupt 4. A rising edge on this pin will cause an external interrupt 4 if enabled.
bit 6
Master In Slave Out. For SPI data transfers, this pin receives data for the master and transmits data from the slave.
INT3/MOSI
External Interrupt 3. A falling edge on this pin will cause an external interrupt 3 if enabled.
bit 5
Master Out Slave In. For SPI data transfers, this pin transmits master data and receives slave data.
INT2/SS
External Interrupt 2. A rising edge on this pin will cause an external interrupt 2 if enabled.
bit 4
Slave Select. During SPI operation, this pin provides the select signal for the slave device but does not control the
output drive of MISO.
TXD1
Serial Port 1 Transmit. This pin transmits the serial Port 1 data in serial port modes 1, 2, 3, and emits the synchro-
bit 3
nizing clock in serial port mode 0.
RXD1
Serial Port 1 Receive. This pin receives the serial Port 1 data in serial port modes 1, 2, 3, and is a bidirectional data
bit 2
transfer pin in serial port mode 0.
T2EX
Timer 2 Capture/Reload Trigger. A 1 to 0 transition on this pin will cause the value in the T2 registers to be
bit 1
transferred into the capture registers, if enabled by EXEN2 (T2CON.3, SFR C8h). When in auto-reload mode, a 1
to 0 transition on this pin will reload the Timer 2 registers with the value in RCAP2L and RCAP2H if enabled by EXEN2
(T2CON.3, SFR C8h).
T2
Timer 2 External Input. A 1 to 0 transition on this pin will cause Timer 2 to increment.
