Notes:
1. C9~C12 depends on LCD panel dot size.
2. Option R5 equals to 100Ω if high noise immunity is needed.
3. For DAC option application.
4. To ensure that three batteries function well in W536F20 demo board. C₆ should stay close to 5. pad PWM/PWM2 at its best.
Under the mask ROM version, C₅ and C₆ can be skipped.
5. Sure chip operation properly, please bond all V_DDP, V_DD, V_SSP and V_SS; and connect V_SSP pad to V_SS from external PCB circuit.
