In addition to automatic offset calibration, the
MAX1497/MAX1499 offer a user-defined custom offset
16-bit read/write register. The final result of the ADC
conversion is the input after autocalibration minus
the value in the custom offset. The custom offset value
is stored in this register. D15 is the MSB. The data is
represented in two’s complement format.

ADC result register 1 is a 16-bit read-only register. This
register stores the 16 MSBs of the ADC result. The data
is represented in two’s complement format.
For the MAX1499, the data is 16-bit and D15 is the
MSB. For the MAX1497, the data is 12-bit, D15 is the
MSB, and D4 is the LSB.
Default values: 0000h
The LED data register is a 16-bit read/write register.
This register updates from ADC result register 1 or from
the serial interface by selecting the SPI/ADC bit in the
control register. The data is represented in two’s com-
plement format.
For the MAX1499, the data is 16-bit and D15 is the
MSB. For the MAX1497, the data is 12-bit, D15 is the
MSB, and D4 is the LSB, followed by 4 trailing sub-bits.

ADC result register 2 is an 8-bit read-only register. This
register stores the 4 LSBs of the ADC result.
Use this result with the result in ADC result-register 1 to
form a 20-bit two’s complement conversion result.
