Note: All bits in these register are latched. This register does not create interrupts. See
Bit 7: Receive Pulse Density Violation Event (RPDV). Set when the receive data stream does not meet the ANSI
T1.403 requirements for pulse density.
Bit 5: Change of Frame Alignment Event (COFA). Set when the last resync resulted in a change of frame or
multiframe alignment.
Bit 4: Eight Zero Detect Event (8ZD). Set when a string of at least eight consecutive zeros (regardless of the
length of the string) have been received.
Bit 3: Sixteen Zero Detect Event (16ZD). Set when a string of at least 16 consecutive zeros (regardless of the
length of the string) have been received.
Bit 2: Severely Errored Framing Event (SEFE). Set when two out of six framing bits (Ft or FPS) are received in
error.
Bit 1: B8ZS Codeword Detect Event (B8ZS). Set when a B8ZS codeword is detected at RTIP and RRING
independent of whether the B8ZS mode is selected or not. Useful for automatically setting the line coding.
Bit 0: Frame Bit Error Event (FBE). Set when a Ft (D4) or FPS (ESF) framing bit is received in error.
