Function

• 1/2 VDD voltage generator used for the analog system

ground

28

Vref

A capacitor of about 10 µF must be connected between

Vref and AVSS (VSS) to minimize power supply ripple.

TIM

If no zero cross is recognized between the time the data is

stored and the time this timer completes, the data is

acquired forcibly.

• Chip enable
