Bit 20:

Cipher Enable: When set, the internal M6 cipher will encrypt the application packets with the associated key in the
M6 indirect address space for the given EMI value assigned. When the EMI value changes the cipher will
automatically change the key on the next application packet. Writes to the ODD/EVEN bit (bit 1 will automatically
swap the odd/even key in the cipher.
Note:
the maximum average data rate for the M6 cipher is 60 Mbps.
Tag: Tag code to insert in isochronous bus packet header. Should be ‘01’ for IEC 61883 International Standard data.
Channel: Isochronous channel number.
Speed: Cable transmission speed (S100, S200, S400).

Encryption Mode Indication: This bit pattern specifies the level of copy control information for the data stream. The
field only has significance when the internal cipher is enabled (CPHR_EN = 1). The bits are read only and follow the
value of the AVxEMI pins when EMI_PE = 1 (bit 19). The bits are read/write when EMI_PE = 0. See the “5C Digital
Transmission Content Protections Specification, Volume 1”for more details about EMI values.
Odd even bit used for encryption key (0 = even, 1 = odd). When the internal M6 cipher is enabled (CPHR_EN = 1), a
write that changes this bit field will cause the cipher to swap its odd/even key. The key will be changed on the very
next application packet and an interrupt (ODDEVN) will be generated. See the “5C Digital Transmission Content
Protection Specification, Volume 1”for more details about odd/even values. When the internal cipher is not enabled
(CPHR_EN = 0) the bit value is R/W and the current bit value will be transmitted in the isochronous header.
SY: Sync code to insert in SY field of isochronous bus packet header. This bit reflects the value of the AVx SY pin
and is synchronized with the data payload that was associated with it.

The AV Transmitter Memory Status register reports on the condition of the internal memory buffer used to store incoming AV data streams
before transmission over the 1394 bus. This register is used primarily for diagnostics; several memory status flags are also available in the
ITXINTACK register.
