FUNCTION
For 3 battery(3.3V~5.5V) application ,add the capacitor 0.1uF to shunts
between CVDD and GND as power stability for regulator output.
For 2 battery(2.2V~3.6V) application, CVDD will connect to VDD directly.
High voltage for embedded OTP programming
Note: As program OTP, the BP00 ~ BP03, VDD, VSS, CVDD, RESETB and VPP pin will be used

Notes:
1. The block (1): Please refer to (a) and (b) circuits for two-battery or three-battery application.
2. The block (2): The low-pass filter circuit is necessary for VDD stability, in order to avoid VDDSPK noise.
3. The block (3): The capacitor, 4.7uF, shunted between VDD and GND is necessary for power stability. However the
value of capacitor depends on the power loading of the application
4. The block (4): Cp1 and Cp2 (15~30pF) are optional for main Crystal, which can be skipped normally.
5. The block (5): The Rs value is suggested of 270 ~ 1K to limit large DAC output current flowing into transistor.
6. Cp3 and Cp4 (15~30pF) are optional for 32KHz Crystal, which can be skipped normally.
7. Please connect all VDD pins include VDDOSC/VDD_BP1 to VDD. If with SIM application, the VDD_BP1 pin can
connect to different voltage for SPI flash or W551Cxx and the BP10~BP17 also use the same power VDD_BP1.
8. The above application circuit is for reference only. No warranty for mass production.
9. Other application circuits please refer to Design Guide.
