LCD common signal output pads either 1/16 duty or 1/8 duty. The LCD frame rate
is controlled by LCDM1 register, and default value LCDM1=0111b with 64Hz
frame rate.
LCD common signal output pads, or shared as general output by register
LCDM3.2 when in 1/8 duty mode. Default function is common function.
LCD common signal output pads, or shared as general input by register LCDM3.2
when in 1/8 duty mode. Default function is common function and PM5.2=0 to
inhibit LCD waveform abnormal.
Connection terminal for voltage double capacitor with 0.1uF. The DH2 connects
to capacitor positive node and DH1 negative node if polar capacitor is used.
LCD COM/SEG output driving voltage. Need an external 0.1uF capacitor to every
pad terminal.
Voltage regulator output pad. An external capacitor is a must. Output level can
be controlled from 0~Fh by LCDM4 register. If internal pump is enabled
(LCDM3.3=0 and default value), LCD operating voltage (VLCD) will be 4*V2 or
5*V2 depending on 1/4 bias or 1/5 bias. A limitation should be noted that VLCD
must be higher than (VDD-0.5v) to avoid chip leakage current. While external
reference voltage is selected (LCDM3.3=1), V2 pad input voltage can not be over
1.5 Volt to inhibit chip damage.
Power ground for PWM or DAC playing output.
Power ground
Power source for PWM or DAC playing output.
Power ground.
(4) RD1~3 are shared as RDP/SPDATA/WRP to interface with W55XXX @W536030A/060A
(5) @W536120A only
(6) 0.1uF is default value, and capacitor value should be larger than 0.1uF if LCD dot size over
0.5mm * 0.5mm.
(7) External application circuit should connect together, please refer to APPLICATION CIRCUIT. To
sure chip operation properly, please bond all VDD, VDDP,VSS and VSSP pads and connect VSS
and VSSP from chip outside PCB circuit.
