4. PAD DESCRIPTION
SYMBOL
I/O
FUNCTION
XIN/RXIN
Input pad for main clock oscillator. It can be connected to crystal when
crystal mode is selected (SCR0.2=1), otherwise connect a resistor to
I
VDD to generate main system clock while Ring mode is selected
(SCR0.2=0 and default). Oscillator can be enabled or stopped by set
SCR0.1 to 1 or clear to 0 separately. External capacitor connects to
start oscillation and get more accurate clock when crystal mode
XOUT
Output pad for oscillator which is connected to another crystal pad
O when in crystal mode. External capacitor connects to start oscillation
when in crystal mode.
X32I/RSUB1
32.768 KHz crystal input pad or external resistor node 1 by mask
I option. External 15~20pF capacitor connects to start oscillation and
get more accurate clock when in crystal mode.
X32O/RSUB2
32.768 KHz crystal output pad or external resistor node 2 by mask
O option. External 15~20pF capacitor connects to start oscillation when
in crystal mode.
General Input/Output port specified by PM1 register. If output mode is
RA0 ~ RA3/TONE
(4)
I/O
selected, PM0 register bit 0 can be used to specify CMOS/NMOS
driving capability option. Initial state is input mode. RA3 may be uses
as TONE if bit 0 of MR0 special register is set to logic 1. An interrupt
source.
RB0 ~ RB3
(4)
General Input/Output port specified by PM2 register. If output mode is
I/O selected, PM0 register bit 1 can be used to specify CMOS/NMOS
driving capability option. Initial state is input mode.
RC0 ~ RC3
4-bit schmitter input with internal pull high option specified by PM3
I
register bit 2. Each pad has an independent interrupt capability
specified by PEFL special register. Interrupt and STOP mode wake up
source. RC0 is also the external event counter source of Timer1.
RD0 ~ RD3
4-bit schmitter input port with internal pull high option specified by PM3
I
register bit 3. Each pad has an independent interrupt capability
specified by PEFH special register. Interrupt and STOP mode wake up
source.
RE0~RE3
(4)
O
Output port only. PM3 register bit 0 can be used to specify
CMOS/NMOS driving capability option.
RF0~RF3
(4)
O
Output port only. PM3 register bit 1 can be used to specify
CMOS/NMOS driving capability option.
RG0 ~ RG3
I
Input port with internal pull high option specified by PM6 register bit 0.
(W536090P/W536120P only)
RH0 ~ RH3
(4)
O
Output port only. PM6 register bit 1 can be used to specify
CMOS/NMOS driving capability option. (W536090P/W536120P only)
RES I System reset pad, active low with internal pull-high resistor.

Notes:
1. Option R5 equals to 100if high noise immunity is needed.
2. For DAC option application.
3. To ensure that three batteries function well in W536F20 demo board. C6 should stay close to pad PWM/PWM2 at its best.
Under the mask ROM version, C5 and C6 can be skipped.
4. Sure chip operation properly, please bond all VDDP, VDDA, VDD, VSSP, VSSA and VSS; and connect VSSP pad to VSS from external
PCB circuit. VDDA, VSSA are only for W536090P/120P.
