LBACP,LBDCP:

The LBACP and LBDCP bits indicate when the corresponding loopback code

is present during a 39.8 ms interval.

LBAE:

The LBAE bit enables the assertion or deassertion of the inband Loopback

Activate (LBA) detect indication to generate an interrupt on the INTB pin.

When LBAE is set to logic 1, any change in the state of the LBA detect

indication generates an interrupt. When LBAE is set to logic 0, no interrupt is

generated by changes in the LBA detect state.

LBDE:

The LBDE bit enables the assertion or deassertion of the inband Loopback

Deactivate (LBD) detect indication to generate an interrupt on the INTB pin.

When LBDE is set to logic 1, any change in the state of the LBD detect

indication generates an interrupt. When LBDE is set to logic 0, no interrupt is

generated by changes in the LBD detect state.

LBAI,LBDI:

The LBAI and LBDI bits indicate which of the two expected loopback codes

has changed state. A logic 1 in these bit positions indicate that a state

change in that code has occurred; a logic 0 in these bit positions indicate that

no state change has occurred.
