Reg 1AH to Reg 1CH will be loaded with the number of BIP 8/24 (B2) errors from an internal counter approximately 1 s after
a write operation is done to Reg 1AH, Reg 1BH, Reg 1CH, Reg 1DH, Reg 1EH, Reg 1FH, or Reg 00H. At that time (1 s
after the write operation), these three registers are updated and the internal BIP 8/24 error counter is reset to zero to begin
another round of error accumulation. Reading Reg 1AH, Reg 1BH, and Reg 1CH after the write yields the number of BIP 8/24
(B2) errors accumulated since the counter was last reset, if overflow has not occurred.

Reg 1DH, Reg 1EH, and Reg 1FH will be loaded with the number of line FEBE (Z2) errors from an internal counter approx-
imately 1 s after a write operation is done to Reg 1AH, Reg 1BH, Reg 1CH, Reg 1DH, Reg 1EH, Reg 1FH, or Reg 00H.
At that time (1 s after the write operation), these three registers are updated and the internal line FEBE error counter is reset
to zero to begin another round of error accumulation. Reading Reg 1DH, Reg 1EH, and Reg 1FH after the write yields the
number of line FEBE (Z2) errors accumulated since the counter was last reset, if overflow has not occurred.
