9I2C-BUS CONTROL AND STATUS REGISTERS

Tables 13 to 26 list the I2C-bus instructions intended for functional control and status.

Column M identifies the SAA6752HS modes that are valid for each I2C-bus instruction. The key is:

I - write and/or read valid in Idle mode

P- write and/or read valid in Paused mode

S - write and/or read valid in Stop mode

E - write and/or read valid in Encode mode

All - write and/or read valid in Idle, Encode, Paused and Stop mode.

Table 13 I2C-bus control

Note

1. Paused mode transitions are not applicable to transport stream and DIO output mode combination, only transport stream and DEBI output mode

combination.

Enables SAA6752HS to time-out to Idle mode

if STOP to IDLE transition cannot be

completed (i.e. due to no video signal being

present). If a general error event is detected,

the SAA6752HS will automatically switch to

Idle mode via forced reconﬁgure.
