18.3.14 CRC Error Frame Receive Counter Register (CEFCR)
CEFCR is a 32-bit counter that indicates the number of times a frame with a CRC error was
received. 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.
18.3.15 Frame Receive Error Counter Register (FRECR)
FRECR is a 32-bit counter that indicates the number of frames for which a receive error was
indicated by the RX-ER input pin from the PHY-LSI. FRECR is incremented each time the RX-
ER pin becomes active. 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.
18.3.16 Too-Short Frame Receive Counter Register (TSFRCR)
TSFRCR is a 32-bit counter that indicates the number of frames of fewer than 64 bytes that have
been received. 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.
