Description
RESET: Resets the TDA9950. Any transmission in progress
will be completed first - the reset occurs once the TDA9950
returns to the idle state. All default values will be restored.
0 = no specific action.
1 = resets the TDA9950.
ON_OFF:
0 = the TDA9950 is disabled (after completion of any pending
CEC transmission or reception) and will no longer
acknowledge any message on the CEC line or accept any
message for transmission.
1 = the TDA9950 is enabled and will acknowledge messages
according to the logical address bits in the CEC Address ACK
High and CEC Address ACK Low registers.
