mod1_seq1_sub5_pdsel

R/W

This bit assigns the photodiode input for

ADC modulator 1 in sequencer 1 for

subsample 5. Each bit represents one

photodiode input whereas the LSB

represents PD1 and the MSB represents

PD3 input.

001: PD1 assigned to ADC modulator

010: PD2 assigned to ADC modulator

100: PD3 assigned to ADC modulator

mod2_seq1_sub5_pdsel

R/W

This is the input source selection bit for ADC

modulator 2. If this bit is set to zero, the

photodiode inputs can be assigned to

modulator 2 in sequencer 1 for subsample 5.

If this bit is set to one the AFE function block

is connected to ADC modulator 2 in

sequencer 1 for subsample 5 to measure

various input sources.

0: Photodiode inputs assigned to ADC

1: AFE inputs assigned to ADC modulator 2

2:0

Depending on register bit

mod2_seq1_sub5_pdsel[3] the register bits

mod2_seq1_sub5_pdsel[2:0] support a

different function.

If mod2_seq1_sub5_pdsel[3] is set to 0 the

ADC modulator 2 in sequencer 1 for

subsample 5:

001: PD1 connected to ADC modulator 2

010: PD2 connected to ADC modulator 2

100: PD3 connected to ADC modulator 2

If mod2_seq1_sub5_pdsel[3] is set to 1 the

AFE function block is connected to ADC

modulator 2 in sequencer 1 for subsample 5

and allows for the following input

configuration:

000: LED 1

001: LED 2

010: LED 3

011: VCSELS

100: VCSELA

101: PGND

110: VDD

111: ITEMP
