Details:

Performing a UDMAP TX channel teardown of SA2UL can result in undefined behavior on the PSIL channel.

Workaround(s):

There are two software workarounds:

1. Follow TX Channel Teardown by a teardown of the pairing registers (including clearing the enable bit in PSIL register 0x2), and re-pairing of the channel.
2. Suppress teardown packet generation of the channel via the Tx Channel N Configuration Registers.
