Default value at power-on reset
8-bit General purpose input/output pins
Default value at power-on reset
5-bit General purpose input/output pins
Default value at power-on reset
External interrupt pin triggered by falling edge
8-bit Analog-to-Digital Converter
Defined by AISR (Bank 2 R8) <0 : 7>
Pulse width modulation outputs
Defined by PWMCON (Bank 1-R5)<5 : 7>
Buzzer output driver
External reference voltage for ADC
Defined by ADCON (Bank 2 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 CMPCON (IOCA) <0:1>
General-purpose Input only
If it remains at logic low, the device will be reset
Wake-up from sleep mode when pin status changes
Voltage on /RESET must not exceed Vdd during normal
mode
Real time clock/counter with Schmitt Trigger input pin. It
must be tied to VDD or VSS if not in use.
Counter 1 / Counter 2 with Schmitt Trigger input pin.
Sin pin is used to input serial data signals by software.
Sin pin is also used as Port P82.
Sout pin is used to input serial data signals by software.
Sout pin is also used as Port P81.
Sck pin is used to input and output synchronous clock
signals for serial data transfer by software.
Sck pin is also used as Port P80.
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.
