Section 18 Ethernet Controller (EtherC)
18.3.11 Delayed Collision Detect Counter Register (CDCR)
CDCR is a 32-bit counter that indicates the number of all delayed collisions that accured on the
line after the start of data transmission. When the value in this register reaches H'FFFFFFFF,
count-up is halted. The counter value is cleared to 0 by a write to this register with any value.
18.3.12 Lost Carrier Counter Register (LCCR)
LCCR is a 32-bit counter that indicates the number of times the carrier was lost during data
transmission. When the value in this register reaches H'FFFFFFFF, the count is halted. The
counter value is cleared to 0 by writing to this register with any value.
18.3.13 Carrier Not Detect Counter Register (CNDCR)
CNDCR is a 32-bit counter that indicates the number of times the carrier could not be detected
while the preamble was being sent. When the value in this register reaches H'FFFFFFFF, the count
is halted. The counter value is cleared to 0 by a write to this register with any value.
