FUNCTIONAL DEVICE OPERATION
ADC SUBSYSTEM
ADC ARBITRATION
store both their results as shown in
access to the control of 'ADC BIS' is handled via the ADCBISn bits located at bit position 23 of the ADC control registers, which
functions as an extended address bit. By setting this bit to a 1, the control bits which follow are destined for the 'ADC BIS'.
ADCBISn will always read back 0 and there is no read access to the control bits related to 'ADC BIS'. The read results from the
'ADC' and 'ADC BIS' conversions are available in two separate registers.

The ADC converter and its control is based on a single ADC converter core with the possibility to store two requests, and to
The programming for the two requests, the one to the 'ADC' and to the 'ADC BIS', uses the same SPI registers. The write
The following diagram schematically shows how the ADC control and result registers are set-up.
