CRC Error Count Operation (CRC Count Visibility = 1)
The CRC error counter is merged into a 16-bit counter and increments each time the MAC Transceiver detects a CRC error
when the CRC Error Count Visibility bit of PHY Test Register 1 (see
1EH)" on page
480) is set. This counter freezes at the maximum value FFFFh. The counter automatically clears when read.
