Bit 63-0 Parameters Channel buffer, byte 0-7:
8 bytes for the answer to a long message (read operation) or for a "long message" write
operation.
Bit 63-48
Error report for a long message, byte 0-1:
2 bytes for reports about errors in encoder resources arising from the previous "long
message" operation.
6.3.18 Long message address
The addresses and the addressing mode for "long messages" sent over the Parameters
Channel are determined in the PC_ADD_H/PC_ADD_L long message address registers.
In addition, the long message address register 28h (PC_ADD_H) contains indications of
errors arising from "long message" operations. For this sort of error, the Parameters
Channel buffer contains the error code in bytes 0 and 1 associated with this status (see
chapter 7.6.6).

Bit 15 LID: Long message identification. This is a read only bit that will always return ‘1’ when
read.
Bit 14 LRW: Long message, read/write mode
1 = "long message" read operation
0 = "Long message" write operation
Bit 13
LOFF: Long message addressing mode/long message error Write access:
1 = Offset addressing of "long messages". The offset value from the PC_OFF_H/
PC_OFF_L registers is used in the resource of the selected database entry as a sub-
address.
0 = Addressing of "long messages" without offset. The offset value from the PC_OFF_H/
PC_OFF_Lregisters is not used.
Read access:
1 = The last "long message" caused an error.
