Notes:
(1) C9~C14 depends on LCD panel dot size.
(2) Option R5 equals to 100
if high noise immunity is needed.
(3) For DAC option application.
(4) To ensure that three batteries function well in W536F20 demo board. C

should stay close to pad PWM/PWM2 at its
best. Under the mask ROM version, C
5
and C

can be skipped.
(5) Sure chip operation properly, please bond all V

; and connect V

pad to V
SS
from external PCB
circuit.
(6) Main clock with Ring type, the frequency deviation is depended on VDD and resistor
