5. PIN DESCRIPTION
SYMBOL
I/O
FUNCTION
XIN
I
Input pin for oscillator.
Connected to crystal or resistor to generate system clock by code option.
External 10~20pF capacitor uses to get accurate freq in crystal mode.
Output pin for oscillator.
Connected to crystal or resistor to generate system clock by code option.
20pF capacitor is built in internal for crystal mode.
XOUT
O
RA0
RA3
I/O
Input/Output port. Input/output mode specified by port mode 1 register
(PM1). When used as output port, can provide high sink current for driving
LED.
RB0
RB3
I/O
Input/Output port. Input/output mode specified by port mode 2 register
(PM2). When used as output port, can provide high sink current for driving
LED.
RC0
RC3
I/O
Input/Output port. Input/output mode specified by port mode 4 register
(PM4). Each pin has an independent interrupt capability in input mode.
And build-in schmitt trigger.
RD0
RD3
I/O
Input/Output port. Input/output mode specified by port mode 5 register
(PM5).
RE0/DOUT
RE1/CLKO
RE2/DIN
RE3/CLKI
I/O
Special input/output port.
This port can be configured by software to act as the output of internal
port RT or the serial I/O port. When used as output port, can provide high
sink current for driving LED.
MFP
O
Output pin only. This pin can output modulating or nonmodulating
frequency, or Timer 1 clock output specified by mode register 1 (MR1).
INT
I
External interrupt pin with pull-high resistor.
RES
V
DD
I
System reset pin with pull-high resistor.
I
Positive power supply (+).
V
SS
I
Negative power supply (-).
