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.
XOUT
O
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.
RA0
RA2,
RA3 (DATA)
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.
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
(MODE)
1
I
External interrupt pin.
This pin must be tied to V
DD
through an external resistor. It is a low active
and floating input pin.
RES
(V
PP
)
1
I
System reset pin.
This pin must be tied to V
DD
through an external resistor when it is not
used to reset this chip. It is a low active and floating input pin.
V
DD
I
Positive power supply (+).
V
SS
I
Negative power supply (-).
Note: There are internal pull-high resistors in these pins of W741C20X.
