Reserved | 31:10 | roRead-only | 0x0 | Reserved, read as 0, ignored on write. |
count | 9:0 | rwNormal read/write | 0x0 | Carrier sense errors - a 10 bit register counting the number of frames transmitted where carrier sense was not seen during transmission or where carrier sense was deasserted after being asserted in a transmit frame without collision (no under run). Only incremented in half duplex mode. The only effect of a carrier sense error is to increment this register. The behaviour of the other statistics registers is unaffected by the detection of a carrier sense error. |
