Bit Description

7low_vdd_rst

R/W

0: At the end of a movie or a display picture the “low_

VDD” flag is not changed

1: At the end of a movie or a display picture, the “low_

VDD” flag is set to “0”

low_vdd_stat

R/W

This bit indicates the supply status

0: If low_VDD is detected, the Interrupt Status

triggered.

1: The low_VDD bit is directly mapped to the pin IRQ.

This can be used to control an external DC/DC

Converter or Charge Pump. In this case pin IRQ

cannot be used for interrupt functionality, the

Interrupt Status Register will be updated accordingly.

led_error_

correction

0R/W

This bit defines the LED open handling

0: Open LEDs which are detected at LED open test,

are NOT disabled

1: Open LEDs which are detected at LED open test,

are disabled

dot_corr

R/W

Analog current DotCorrection(1)

0: Disabled

1: Enabled
