WakeRES
Description
Wakes up from rest with FPD
0 = FPD rest wake up disabled
1 = Wake up when fi nger is present OR motion is detected
2 = Wake up when fi nger is present AND motion is detected
In FPD enabled mode, cut off motion when fi nger is not detected and shutter is
below preset value.
Shutter preset value can confi gured by SHUT_CUTOFF_THRES in FPD_CTRL
(register 0x75).
0 = Disable FPD_Mot_Cut
1 = Enable FPD_Mot_Cut
Enable this bit for PAD_STATUS check
To improve FPD on low refl ectance surface by comparing the instantaneous
Squal value with a threshold set in FPD_SQUAL_THRESH (register 0x78).
0 = Disable FPD_SQ_EN
1 = Enable FPD_SQ_EN
Description
Sets resolution when sensor wakes up from rest modes. Eff ective only when
speed switching is enabled.
