Description

READY

0: Internal controller is initializing after reset

1: Internal controller is ready

ERROR

0: The video mode parameters are all within range

1: A video mode parameter is out of range and the mode cannot be

calculated. The following conditions cause an error:

IHC < 32

IVC < 32

HAT < 20%

VAT < 20%

TVP < 128

TVL < 128

MCS

Mode Change Start

0: Video mode change is not in progress.

1: Video mode change is in progress.

The internal micro-controller sets this bit to 1 after it detects a change

in the size or speed of the input video mode. The controller clears this

bit after it has completed the calculations for the new mode.

MCC

Mode Change Complete

0: Video mode change is not complete

1: Video mode change is complete

NOTE: This bit is set when a mode change is complete and cleared by

writing a 1 to the CLRMCC bit in the SCR

ICALAQRD

Input Calibration Acquired

0: The internal micro-controller has not yet read an acceptable set of

values from the SHV, EHV, SVV, and EVV registers and is using the

default values for HAT, SHV, VAT, and SVV.

1: The internal micro-controller has read acceptable input calibration

values and is using them.

VSYNCSACT

0: No VSync activity during last 100ms interval.

1: VSync activity during last 100ms interval was detected.

HSYNCACT

0: No HSync activity during last 100ms interval.

1: HSync activity during last 100ms interval was detected.

Internal micro-controller ROM and RAM checksum.

NOTE: The checksum for version 30 is 0xAF.

NOTE: It is possible to write to this register, however doing so will produce unpredictable results.
