24/51

Note 50: With exception of

HDUTY and BREF adjustments data that can take effect instantaneously if switches

HDutySyncV and B+SyncV are at 0 respectively.

Note 51: In Read Mode, the device always outputs data of the status register, regardless of sub address previously

selected.

Note 52: The TV, TH, TVM and THM bits are for testing purposes and must be kept at 0 by application.

Description of I2C Bus switches and flags

Write-to bits

Sad00/D7 - HDutySyncV

Synchronization of internal application of Hori-

zontal Duty cycle data, buffered in I2C Bus latch,

with internal discharge of Vertical oscillator

0: Asynchronous mode, new data applied

with ACK bit of I2C Bus transfer on this sub

address

1: Synchronous mode

Sad02/D7 - HMoiré

Horizontal Moiré characteristics

0: Adapted to an architecture with EHT gener-

ated in deflection section

1: Adapted to an architecture with separated

deflection and EHT sections

Sad03/D7 - B+SyncV

Same as HDutySyncV, applicable for B+ refer-

ence data

Sad04/D7 - HDyCorTr

Tracking of Horizontal Dynamic Correction

waveform amplitude with Horizontal Size at ad-

justment and EHT variation (voltage of HEHTIn).

0: Not active

1: Active

Sad05/D7 - HDyCorPh

Phase of start of Horizontal Dynamic Correction

waveform (and B+ drive if in internal sawtooth

configuration) in relation to horizontal flyback

pulse.

0: Start of the flyback

1: Middle of the flyback
