The duration of the blank time can be set to three different timings in order to avoid any
wrong detection of failures during an inrush phase when switching on the load. During this
time the diagnostics doesn’t report any failures.
Note:
The Blanking time is started by turning the selected channel on. Write command to address
0x00 with a ‘1’ (former state ‘0’ => OFF).
If a channel is in on-state (ON_OFF reg = ‘1’), the corresponding BLK_TIMEx register is
write protected.
Note:
This blanking time is just used for analog devices and is related to the analog device
connected to the device (see VIP specification).
If a channel is in ON-state (ON_OFF reg = ‘1’), the corresponding TD_SENSE register is
write protected.
