Description
0
RO
Reserved. Set to 0.
If set, do electrical offset calibration (diodes
disabled) instead of optical. Otherwise, do
optical calibration. In either case, the result is
stored in the POFFSET_L/H registers. This flag is
cleared after calibration is completed.
0
RW_SM This flag is redundant, software could just:
set gdiode_disab=0xf set concap_intinn=1 start
calibration. However, since electrical calibration
is done automatically at the first time PON gets
asserted, the function is there anyway, so it's
made available to the user here.
0
WS_SC Reserved. Set to 0.
Start Offset Calibration. The result is stored in the
0
RW_SM
POFFSET registers. The calib_finished flag is
asserted afterwards. Calibration can be stopped
by writing a 0 to this bit.
