22/47

Note 44: With exception of

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

HDutySyncV and B+SyncV are at 0 respectively.

Note 45: In Read Mode, the device always outputs data of the status register, regardless of sub address previously

selected.

Note 46: The TV, TH, TVM and THM bits are for testing purposes and must be kept at 0 by application.
