Bit 7

Reserved: Must be set to 0.

Bits [6:5]

Reserved: Must be set to 00.

OVERDRIVE_MO

This bit is used for a special proprietary mode between the STV2310 and the STV3500. It is called

overdrive mode. Additional VBI data is stuffed between the EAV and the SAV to raise the output clock data.

0: Overdrive output mode disabled

1: Overdrive output mode enabled

OVERDRIVE_

SEL[1:0]

Selection of frequency shift in the overdrive mode

It is only active when the overdrive mode has been selected.

The n value provided by the OVERDRIVE_SEL[1:0] register will determine the number of bytes added in

each preamble according to: number of bytes added = n x 32 bytes.

Bit 1

Reserved: Must be set to 0.

Bit 0
