Decoupling capacitor

(0.01µF to 1µF)

It should be used smoothing capacitor for between AVR1 to AVRL1, RVR0 to RVRL0,

RVR1 to RVRL1 as well.

− CREF capacitor size and A/D converter activation time

It depends on activation time of A/D converter with R/D converter and activation time of

4 channels same time sampling A/D converter by CREF capacitor seize. The

computation expression of activation time is as follows.

Activation time = 9 × CREF × 1.2k + 1μ [s]

Activation time relate with following time from activation trigger, please use smoothing

capacitor with system operation conditions.

If A/D converter of 4 channels same time sampling,

Set to "1" for ENBL bit of A/D enable setting register.

If A/D converter with R/D converter,

Set to "1" for RDCEN bit of operation control register 1.
