Notes:
1. Option R5 equals to 100Ω if 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 V_DDP, V_DDA, V_DD, V_SSP, V_SSA and V_SS; and connect V_SSP pad to V_SS from external
PCB circuit. V_DDA, V_SSA are only for W536090P/120P.
