Function
8-bit General purpose input/output pins
Pull-high/pull-down
Wake up from sleep mode when the pin status changes
Default value at power-on reset
8-bit General purpose input/output pins
Open drain
Default value at power-on reset
2-bit General purpose input/output pins
Default value at power-on reset
External interrupt pin triggered by a falling or a rising edge.
Defined by CONT <7>
8-bit Analog-to-Digital Converter
Defined by ADCON (R9) <2:0>
External reference voltage for ADC
Defined by ADCON (R9) <7>.
“-“ : the input pin of Vin- of the comparator
“+” : the input pin of Vin+ of the comparator
Pin CO is the comparator output
Defined by IOC80 <4:3>
General-purpose Input only
If it remains at logic low, the device will be reset
Wake-up fromwww.DataSheet.net/ sleep mode when pin status changes
Voltage on /RESET must not exceed Vdd during normal mode
External Counter input
TCC defined by CONT<5>
TCCA defined by IOC80 <1>
TCCB defined by IOC90 <5>
TCCC defined by IOC90 <1>
Crystal type: Crystal input terminal or external clock input pin
RC type: RC oscillator input pin
Crystal type: Output terminal for crystal oscillator or external
clock input pin.
RC type: Clock output with a duration of one instruction cycle
time. The prescaler is determined by the
CONT register.
External clock signal input.
IR mode output pin.
Capable of driving and sinking current = 20mA when the output
voltage drops to 0.7Vdd at rise to 0.3Vdd at
Vdd = 5V
Power supply
Ground
