Description
P3[2] — Port 3 bit 2.
INT0 — External interrupt 0 input.
P3[3] — Port 3 bit 3.
INT1 — External interrupt 1 input
P3[4] — Port 3 bit 4.
T0 — External count input to Timer/Counter 0.
CEX3 — Capture/compare external I/O for PCA Module 3.
P3[5] — Port 3 bit 5.
T1 — External count input to Timer/Counter 1
CEX4 — Capture/compare external I/O for PCA Module 4
P3[6] — Port 3 bit 6.
WR — External data memory write strobe
P3[7] — Port 3 bit 7.
RD — External data memory read strobe.
Port 4: Port 4 is a 4-bit bidirectional I/O port with internal
pull-ups. Port 4 pins are pulled HIGH by the internal pull-ups
when ‘1’s are written to them and can be used as inputs in this
state. As inputs, Port 4 pins that are externally pulled LOW will
source current (I
P4[0] — Port 4 bit 0.
SCL_1 — Second I
SCK — Serial clock input/output for SPI
P4[1] — Port 4 bit 1.
SDA_1 — Second I
MISO — Master input/slave output for SPI
P4[2] — Port 4 bit 2.
MOSI — Master output/slave input for SPI
P4[3] — Port 4 bit 3.
SS — Slave select input for SPI
Program Store Enable: PSEN is the read strobe for external
program memory. When the device is executing from internal
program memory, PSEN is inactive (HIGH). When the device is
executing code from external program memory, PSEN is
activated twice each machine cycle, except that two PSEN
activations are skipped during each access to external data
memory.
Reset: While the oscillator is running, a HIGH logic state on
this pin for two machine cycles will reset the device.
External Access Enable: EA must be connected to V
order to enable the device to fetch code from the external
program memory. EA must be strapped to V
program execution.
