BIT DESCRIPTION

This statistic register counts the number of times that carrier_sense was not asserted or was de-asserted during the transmission of a frame without collision. Carrier sense is not monitored for the purpose of this statistic until after the preamble and start-of-frame delimiter. This is a 4-bit counter that will stick at 0fh. An UpdateStats interrupt will occur, if enabled, after the counter has counted through 0ch.

Reserved for future use. Should be set to 0.
