For a description of how to use these features, see section 9.1 MPEG Clock Modes on 55.
With MCLKINV = 0, data is clocked out on the positive edge of MOCLK. If MCLKINV = 1, data is clocked out on
the negative edge of MOCLK.

BA LK[2:0] + 2 = Number of bytes for byte aligner to lock.
ERR IND
BKERR remains high when error free MPEG packets are being output on the MDO[7:0] bus. BKERR
goes low when there is no De-scrambler lock OR on the first byte of a packet where uncorrectable
bytes are detected. BKERR will remain low until error free MPEG packets are being output on the
MDO[7:0] bus.
BKERR remains high when error free MPEG packets are being output on the MDO[7:0] bus.
BKERR goes low on the first byte of a packet where uncorrectable bytes are detected and will remain
low until the 188th byte (DVB) or 130th byte (DSS) has been clocked out.

High = Inverted signal on BKERR output pin.
Low = Normal signal on BKERR output pin.
High = Normal signal on MOCLK output pin.
Low = Inverted signal on MOCLK output pin.
High = Enable automatic setting of transport error indicator (TEI) bit in MPEG packet
header byte 2 when the block is flagged as uncorrectable by the Reed-Solomon
decoder. See section 8.2 Data output header format - DVB only. (Not used in DSS).
High = Bit serial output of the MPEG data on MDO0 pin.
Low = Parallel output of the MPEG data on MDO[7:0] pins.
The default register value of 3 is equivalent to 5 good sync words.
