Hi all,
I used to SD1983EVK.
It is bit [2:0] of register 1Bh (Loss of Reference Threshold),
Waits time until a LOR signal stands from loss of H sink inputted,
It seems that waits time until it stands can be set up at 0~7 lines H sink cycle.
The place which actually set up and checked operation,
Although it seems that 0~2 performs weight as a preset value,
Waits time becomes long unusually to 3~7,
Even if it changes a preset value, waits time does not change (it is still unusually long).
Please refer to an attachment waveform.
R1B_00.PNG Preset value 0
R1B_03-07.PNG Preset value 3~7 (a waveform -- it does not change)
Regards,
Hisa Kobayashi.
