Bit Name
Current Field Received by EPPI.
The EPPI_STAT.FLD bit indicates whether the current field being received by the
PPI is field 1 (if clear) or field 2 (if set).
Preamble Error Detected.
The EPPI_STAT.ERRDET bit is useful only in ITU receive modes and indicates if
an error has been detected in the status word of EAV or SAV sequences (if set) or not
(if clear).
PxP Ready Error.
The EPPI_STAT.PXPERR bit is valid only in the RX mode. This bit indicates
whether the incoming PPI data overflows the PxP interface (if set) or not (if clear).
This bit is sticky and must be cleared by software by writing 1 to it.
