Bits 9:0 – CSR[9:0]: Carrier Sense Error

Carrier Sense Error

This register counts the number of frames transmitted with carrier sense was not seen during transmission or where carrier sense was de-asserted after being asserted in a transmit frame without collision (no underrun). Only incremented in half duplex mode. The only effect of a carrier sense error is to increment this register. The behavior of the other statistics registers is unaffected by the detection of a carrier sense error.
