Bit Name RW Description Default

VISIBILITY
RW 1 = receiver NOT_OK counters merged into one 16 bit
counter to count CRC errors instead
(crc errors will only be counted after this bit
is set!)
0 = normal operation
0
14 TRANSMIT ERROR
CODE VISIBILITY
RW 1 = false carrier sense counter counts packets received
with transmit error codes instead
(errors will only be counted after this bit is set!)
0 = normal operation
0
13 COUNTER TEST MODE RW 1 = forces counters into test mode
0 = normal operation
