CMODE
ADC Conversion Mode Bit. This bit selects the ADC conversion
0
mode.
0: Direct mode. The analog inputs specified in the ADC channel
registers are converted sequentially one time. When one set of
conversions is complete, the ADC is idle and waits for a new
trigger.
1: Auto mode. The analog inputs specified in the AMC channel
registers are converted sequentially and repeatedly. When one
set of conversions is complete, the ADC multiplexer returns to
the first channel and repeats the process. In this mode data
should be read synchronously with the DAV terminal.
6:5 CONV-RATE[1:0] ADC Conversion rate bits
00
4
ADC-REF-BUFF ADC Reference Buffer bit. This bit must be set to 1 after device
0
power-up to enable the internal reference buffer driving the ADC.
0: ADC reference buffer is disabled.
1: ADC reference buffer is enabled.
