Description
Configures the 8-bit code value corresponding to temperature threshold
Temp . If the temperature exceeds this threshold, the device enters an
Shutdown
external overtemperature state and shuts down.

CODETEMPShutdown = CODETEMPWakeup + SHUTDWN[3:0] 4
The wakeup temperature code is configured as an offset from the eOTP tem-
perature code and the shutdown temperature code is configured as an offset
from the wakeup temperature code; Temp

Sets the lower saturation limit for the 8-bit temperature code provided to the
color system from the fast low pass filter before it is used for polynomial com-
putations.The lower saturation limit is given by:

Configures the external overtemperature protection (eOTP) dim with tempera-
ture feature, which decreases the second stage dim level once the tempera-
ture measured using the external NTC connected to pin eOTP exceeds the
temperature threshold set using eOTP[4:0], Temp
