00H
Defines the output interface in one byte
(collects all sub parameter bits in one byte).
All states defined are the active states
DIO master mode: SAA6752HS delivers the
clock signal.
DIO slave mode: SAA6752HS receives the
clock signal.
for the DEBI output protocol negative
polarity has to be selected
Selection of high-impedance for output pin.
selection of clock frequency for DIO master
mode
Defines the number of leading null bytes
(00H), which are delivered to the output
before the start of the stream.
Remark: After forced reconfigure command
the default value of 00H will be set.
