AuxAdcData
Title:
Auxiliary ADC Data registers
Address:
(Eight registers) $0x10 to $0x17
Function:
R
Description:
These registers enable the user to inspect the conversion value for each of the four auxiliary
ADCs. There are two read registers per ADC, one to obtain the least significant two bits of the
data, the other for the most significant eight bits. Reading these registers does not affect the
ADC conversion cycle. Reading the MSB read register directly reads the ADC output and
simultaneously causes the two bits in the LSB read register to be written into a holding register.
This holding register is read when the LSB read register is read. This mechanism is necessary
to allow the user to read MSB and LSB data from the same ADC conversion cycle. If only the
MSB read register is read, the converter can be considered as an 8-bit ADC.
If a 10-bit
conversion is required, the MSB read register must be read first.
