Note 1: The A-D conversion speed is determined by a combination of ADCSPD, ADCSHSL and ADCSHSPD bits and the A-D
Conversion Speed Control Register ADCVSD bit.
Note 2: Setting of this bit is effective when the sample-and-hold function is enabled by ADCSHSL bit.
A-D Scan Mode Registers 1 are used to select operation mode, conversion speed and scan loop when the A-D
Converter is operating in scan mode. The channels selected with the scan loop select bit are scanned sequen-
tially beginning with channel 0 (n-channel scan).
