Group 3 Register Map (Cont.)
When read, the Reed-Solomon Corrected Error Count (CEC) register
presents the corrected byte or bit error count since it was last reset. The
bit or byte error count is a function of the RS_Bit/Byte_Select
configuration bit (Group 4, APR 31, D7). When the bit error count mode
is chosen, the value in the register represents the bit error count, which
is the CEC multiplied by eight. When written, the register is reset to 0.
The CEC field is 16 bits long. The LSB is located at APR 0, bit 0, and
the MSB at APR 1, bit 7. The CEC count saturates (stops) when it
reaches its maximum count (65,535), and the counter is not reset after
it is read. When the register is written, the CEC bits are cleared to 0.
