McASP IO Pad Loopback Not Functional

CRITICALITY

Low

DESCRIPTION

Due to timing issues, the IO pad loopback feature of the McASP, configured by setting DLBEN=1 and IOLBEN=1 in the MCASP_LBCTL register, will sometimes result in corrupt serializer data.

This feature is intended for development only. All McASP instances are potentially affected.

WORKAROUND

Use digital loopback, which is logically equivalent. Digital loopback is configured by setting DLBEN=1 and IOLBEN=0b in the appropriate MCASP_LBCTL register.
