Wake-up
Pull-high
Buzzer
PFD
Bidirectional8-bitinput/outputport.Eachbitcanbeconfiguredaswake-upin-
put by option. Software instructions determine the CMOS output or Schmitt
Trigger input with or without pull-high resistor (determined by pull-high op-
tions: bit option). The BZ, BZ and PFD are pin-shared with PA0, PA1 and
PA3, respectively.
PB0/AN0
PB1/AN1
PB2/AN2
PB3/AN3
PB4/AN4
PB5/AN5
PB6/AN6
PB7/AN7
I/O
Pull-high
Bidirectional 8-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without pull-high resistor (deter-
mined by pull-high option: bit option) or A/D input. Once a PB line is selected
as an A/D input (by using software control), the I/O function and pull-high re-
sistor are disabled automatically.
PD0/PWM0
PD1/PWM1
PD2/PWM2
PD3/PWM3
I/O
Pull-high
PWM
Bidirectional 4-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without a pull-high resistor (deter-
mined by pull-high option: bit option). The PWM0/PWM1/PWM2/PWM3 out-
put function are pin-shared with PD0/PD1/PD2/PD3 (dependent on PWM
options).
PD4/INT0
PD5/INT1
PD6/TMR0
PD7/TMR1
I/O
Pull-high
Bidirectional 4-bit input/output port. Software instructions determine the
CMOS output, Schmitt trigger input with or without a pull-high resistor (deter-
mined by pull-high option: bit option). The INT0, INT1, TMR0 and TMR1 are
pin-shared with PD4/PD5/PD6/PD7.
VSS
Negative power supply, ground
VLCD
I
LCD power supply
VMAX
I
IC maximum voltage connect to VDD, VLCD or V1
V1, V2, C1, C2
I
Voltage pump
COM0~COM2
COM3/SEG32
O
1/3 or 1/4 Duty
SEG32 can be set as a segment or as a common output driver for LCD panel
by options. COM0~COM2 are outputs for LCD panel plate.
SEG0~SEG31
O
Logical Output
LCD driver outputs for LCD panel segments. SEG0~SEG23 can be optioned
as logical outputs.
OSC1
OSC2
I
O
Crystal or RC
OSC1 and OSC2 are connected to an RC network or a crystal (by options) for
the internal system clock. In the case of RC operation, OSC2 is the output ter-
minal for 1/4 system clock. The system clock may come from the RTC oscilla-
tor.IfthesystemclockcomesfromRTCOSC,thesetwopinscanbefloating.
OSC3
OSC4
I
O
RTC or
System Clock
Real time clock oscillators. OSC3 and OSC4 are connected to a 32768Hz
crystal oscillator for timing purposes or to a system clock source (depending
on the options). No built-in capacitor
