0 = The last "long message" was correctly processed.
Bit 12 LIND: Indirect addressing of long messages
1 = Indirect addressing of "long messages". During this operation, the stored address
content in the given database entry is evaluated.
0 = Direct addressing of "long messages". The operation affects the database entry
given in the current address.
Bit 11-10
LLEN: Data length of the "long message"
11 = 8 data bytes
10 = 4 data bytes
01 = 2 data bytes
00 = No data bytes
Bit 9-0
LADD: Long message address
Database entry with 10 bit address for a "long message" operation.
6.3.19 Long message address offset
The PC_OFF_H/PC_OFF_L address offset registers for long messages are used in "long
message" operations, if LOFF is set in the register 28h. In this case the LOFFADD value
from these registers is used to communicate with the sub-address of a multiple byte
encoder resource.
Only write access is possible for these registers.

R-1 W-0 W-0 W-0 W-0 W-0 W-0 W-0

Bit 15 Bit 8
Register 2Bh:
Long message address offset, byte 0
W-0 W-0 W-0 W-0 W-0 W-0 W-0 W-0
LOFFADD7:0
Bit 7 Bit 0
Bit 15
LID: Long message identification. The value must be "1".
Bit 14-0 LOFFADD14:0: Long message offset value
The 15 bit offset value of the "long message" address offset is stored in these bits.
6.3.20 Parameters Channel control
The PC_CTRL control register for the Parameters Channel handles the start of "long
message" transactions. After setting all "long message" registers (registers
PC_BUFFER0 to 7, PC_ADD_H/PC_ADD_L and PC_OFF_H/L), the "long message" is
transmitted to the DSL Slave by setting the LSTA bit.
Register 2Ch: Parameters Channel control

Bit 7 Bit 0
Bit 7-1 Not implemented: Read as "0".
