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 when
O 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
(9)
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
(9)
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 (W536060K/090K/120K only.)
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
RD1/CLK
RD2/DATA
RD3/ADDR
(4)
4-bit schmitter input port with internal pull high option specified by PM3
register bit 3. Each pad has an independent interrupt capability specified
by PEFH special register. Interrupt and STOP mode wake up source.
RD1~3 will be shared as the external memory W55XXX interface pads
I while RD port shared as serial bus mask option is enabled
@W536020K/030K.
For W536020K/030K only, "Tri-state serial bus" mask option can use to
float ADDR/CLK/DATD while "RD port shared as serial bus" mask option
is enabled.
RE0~RE3
(9)
O
Output port only. PM3 register bit 0 can be used to specify CMOS/NMOS
driving capability option. (W536090K/120K only)
RF0~RF3
(9)
O
Output port only. PM3 register bit 1 can be used to specify CMOS/NMOS
driving capability option. (W536090K/120K only)
