TSXSCY21601: Channel 0 is not working if a PCMCIA is configured and not present on Channel 1

TSXSCY21601 module with a PCMCIA card (TSXSCP111 or TSXCP114) configured in the application (PL7 or Unity Pro).
If the card is not physically in the slot (channel 1), the built-in link (channel 0) does not work.

The module is on error with ERR led flashing.

This a normal behavior of the TSXSCY21601 module.
The module can not work if one channel has a default.
