The pass/fail status of the BIST is stored in the BIST status bit in the PHYCR register. The status bit
defaults to 0 (BIST fail) and will transition on a successful comparison. If an error (mis-compare) occurs,
the status bit is latched and is cleared upon a subsequent write to the Start/Stop bit.
For transmit VOD testing, the Packet BIST Continuous Mode can be used to allow continuous data
transmission, setting BIST_CONT_MODE, bit 5, of CDCTRL1 (1Bh).
The number of BIST errors can be monitored through the BIST Error Count in the CDCTRL1 (1Bh), bits
[15:8].
