6.37 Configuration 55 (Config55) – Address 87

6.38 PLC Dim (PLC_DIM) – Address 89

PLC_DIM sets the second stage dim level while in PLC mode (see "Calibration Mode Operation Code" on

page 22) and Leading-edge Mode. The register value is an unsigned integer in the range of 0

value255. The

dim value prevents flashing when a command is sent to the device. If PLC_DIM = 0x00 then 0x7F is used which

is equivalent to a 50% dim value. The 12-bit PLC dim value is given by:

EOTP_FLP[2:0]

Sets time constant of the faster low pass filter used for filtering the coarse 8-bit

ADCR temperature measurements. This filter's output is used for external

overtemperature fault detection by quickly detecting if the external NTC tem-

perature has exceeded the temperature set point TempShutdown. Its output is

also used by the Color Control System for controlling the color gain with tem-

perature for the temperature-dependent channel.

010 = 466ms

011 = 933ms

100 = 1.866s

111 = Reserved

[2:0]

EOTP_SLP[2:0]

Time constant of the slower low pass filter used for filtering the coarse ADCR

temperature measurements. It's output is used for the external overtempera-

ture protection (eOTP) dim with temperature feature which decreases the sec-

ond stage dim level once the temperature measured using the external NTC

connected to pin eOTP exceeds the temperature threshold set using eOTP,

TempeOTP (see “Configuration 59 (Config59) – Address 91” on page 48).
