Modulator Output Register

The MOD register contains the most recent modulator

data output. The default value corresponds to an

equivalent input of 0V on both ADCs. Each bit in this

of the channels.

This register should be used as a read-only register.

(Note 1).

This register is updated at the refresh rate of DMCLK

(typically, 1 MHz with MCLK = 4 MHz).

See Section 5.4 “Modulator Output Block” for more

details.

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7-4

COMPn_CH1: Comparator Outputs from Channel 1 Modulator bits

bit 3-0

COMPn_CH0: Comparator Outputs from Channel 0 Modulator bits

Note 1:

This register can be written in order to overwrite modulator output data, but any writing here will corrupt the

ADC_DATA on the next three data ready pulses.
