Bit Description

man_sw_itg

If man_mode=1

0: All integrator capacitors are shorted. Integrator is

reset

1: Integrator capacitors are charging up. Integrator is

running

3:1

diode_ctrl

Connection of Photodiodes PD1, PD2, PD3, PD4 to the

photodiode amplifier.

0: PD1-PD4 are connected

1: PD1 synchronous to LED1, PD2 sync/to LED2

PD3 sync/to LED3, PD4 sync/to LED4

2:PD1 synchronous to LED1, PD2 sync/to LED1

PD3 sync/to LED2, PD4 sync/to LED2

3: PD1 synchronous to LED1, PD2 sync/to LED1

PD3 sync/to LED4, PD4 sync/to LED4

4: SPO2 mode *(obsolete): (negedge(sdm1) or

negedge(sdp1)) - PD1=0 PD2=0 PD3=1 PD4=1;

(negedge(sdm2) or negedge(sdp2)) - PD1=1 PD2=1

PD3=0 PD4=0

Note that PD_CFG.pdX takes precedence - to turn OFF

one photo diode, the respective bit has to be de-

asserted in the PD_CFG register.
