Bits 0 to 15: Frame Error Count (FE[15:0]). This count register contains the value of the internal framer error
counter latched during the last error counter update. The internal counter counts either the number of OOF
occurrences or the number of framing bit errors received. The type of counting is configured through the FECC[1:0]
control bits in the T3E3CR2 register. The possible configurations are shown below.
FECC[1:0]
Frame Error-Count Register (FECR1) Configuration
00
DS3 Mode: Count OOF occurrences
E3 Mode: Count OOF occurrences
01
DS3 Mode: Count both F-bit and M-bit errors
E3 Mode: Count bit errors in the FAS word
10
DS3 Mode: Count only F-bit errors
E3 Mode: Count word errors in the FAS word
11
DS3 Mode: Count only M-bit errors
E3 Mode: Illegal state
When the counter is configured to count OOF occurrences, it increments by one each time the framer loses receive
synchronization. When the counter is configured to count framing bit errors, the counter can be configured through
the ECC control bit in the T3E3CR2 register to either continue counting frame bit errors during an OOF event or
not.

Bits 0 to 15: P-Bit Parity Error Count (PE[15:0]). This count register contains the value of the internal P-bit parity
error counter latched during the last error counter update. The internal counter counts the number of DS3 P-bit
parity errors. In E3 mode this counter is meaningless and should be ignored. A P-bit parity error is defined as an
occurrence when the two P bits in a DS3 frame do not match one another or when the two P bits do not match the
parity calculation made on the information bits. Through the ECC control bit in the T3E3CR2 register, the counter
can be configured to either continue counting P-bit parity errors during an OOF event or not.
