Loop-back Mode 2 Auto Enable :
The bit enables local loop-back of the framer while a certain con-
dition is happened.
When this bit is 0:
No local loop-back is activated.
When this bit is 1:
Local loop-back is activated if the following condition happened
from the transmit serial inputs:
•
•
•
Loop-back Mode Release Auto Enable :
The bit enables local loop-back to be released automatically if a
certain condition is happened.
When this bit is 0:
No local loop-back is released.
When this bit is 1:
Local loop-back is released if the following condition happened
from the transmit serial inputs:
•
•
Transmit Sa4 bit[7:0]:
These Read/Write bit fields determine contents of the Sa4 bits
when Transmit Sa4 Enable bit is 0 and Transmit Sa4 Select bit is
1.
Bit 7 of this register is transmitted as Sa4 bit in Frame 2 of the
CRC-4 Multi-frame. Bit 6 of this register is transmitted as Sa4 bit
in Frame 4 of the CRC-4 Multi-frame, etc.
