BRIGHTNESS DETECT REGISTER
(Address (SR5–SR0) = 34H)
T
to read back data in order to monitor the brightness/darkness of
the incoming video data on a field-by-field basis. The brightness
information is read from the I

adjusted.
The luma data is monitored in the active video area only. The
average brightness I

CLKOUT Pin Control (OCR01)
This bit enables the CLKOUT pin when set to 1 and, therefore,
outputs a 54 MHz clock generated by the internal PLL. The
PLL and 4¥ Oversampling have to be enabled for this control to
take effect (MR61 = 0; MR16 = 1).
Reserved (OCR02–03)
A Logic 0 must be written to these bits.
Reserved (OCR04–06)
A Logic 1 must be written to these bits.
