Bit Field Value Description
31-5 Reserved 0 Reads return 0. Writes have no effect.
4-0 G2_CURRENT_
COUNT
CURRENT_COUNT value for the Group2 conversions when enhanced channel selection mode is
enabled. Refer to Section 22.2.2.2.2 for a description of the enhanced channel selection mode.
This register resets to 0 on any of the following conditions:
• A peripheral reset occurs
• An ADC software reset occurs via the ADC Reset Control Register (ADRSTCR)
• G2_CURRENT_COUNT becomes equal to G2_MAX_COUNT
• Application writes zeros to ADG2CURRCOUNT register
• Group2's result RAM is reset
A read from the ADG2CURRCOUNT register returns the value of the current index into the
Group2's look-up table.
