25.16.13 CMPL - ADC Compare register Low
25.17 Register Description - ADC Channel
25.17.1
8077H–AVR–12/09
CTRL - ADC Channel Control Register
• Bits 7:0 - CMP[15:0]: ADC Compare value high byte
These are the 8 MSB of the 16-bit ADC compare value. In signed mode, the number representa-
tion is 2's complement and the MSB is the sign bit.
• Bits 7:0 - CMP[7:0]: ADC compare value high byte
These are the 8 LSB of the 16-bit ADC compare value. In signed mode, the number representa-
tion is 2's complement.
• Bit 7 - START: START Conversion on Channel
Writing this to one will start a conversion on the channel. The bit is cleared by hardware when
the conversion has started. Setting this bit when it already is set will have no effect. Writing or
reading these bits is equivalent to writing the CH[3:0]START bits in
ister A” on page
• Bits 6:5 - Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bits 4:3 - GAIN[2:0]: ADC Gain Factor
These bits define the gain factor in order to amplify input signals before ADC conversion.
