I/O Port 1

is an 8-bit bidirectional port. Port 1 pins can be used

for digital input/output. P1.0 - P1.3 can also be used

as analog inputs of the A/D converter. As secondary

digital functions, Port 1 contains the Timer 2 pins

and the Capture/Compare inputs/outputs. Port 1

pins are assigned to be used as analog inputs via

the register P1ANA.

The functions are assigned to the pins of Port 1 as

follows:

P1.0 / AN0 / T2

Analog input channel 0 /

input to Timer 2

P1.1 / AN1 / T2EX Analog input channel 1 /

capture/reload trigger of Timer

P1.2 / AN2 / CC0 Analog input channel 2 /

input/output of capture/

P1.3 / AN3 / COUT0 Analog input channel 3 /

output of capture/compare

channel 0

P1.4 / CC1

Input/output of capture/

compare channel 1

P1.5 / COUT1

Output of capture/compare

channel 1

P1.6 / CC2

Input/output of capture/

compare channel 2

P1.7 / COUT2

Output of capture/compare

channel 2

I RESET

A high level on this pin for two machine cycles while

the oscillator is running resets the device. An

internal diffused resistor to VSS permits power-on

reset using only an external capacitor to VDD.
