Alignment Errors Register
Register Name:
ALE
Access Type:
Read/Write
• ALE: Alignment Errors
An 8-bit register counting frames that are not an integral number of bytes long and have bad CRC when their length is trun-
cated to an integral number of bytes and are between 64 and 1518 bytes in length (1536 if bit 8, BIG, in network
configuration register, NCFGR, is set, 10240 if bit 3, JFRAME in network configuration register, NCFGR, is set). This regis-
ter is also incremented if a symbol error is detected and the frame is of valid length and does not have an integral number
of bytes.
29.7.28.8
Deferred Transmission Frames Register
Register Name:
DTF
Access Type:
Read/Write
• DTF: Deferred Transmission Frames
A 16-bit register counting the number of frames experiencing deferral due to carrier sense being active on their first attempt
at transmission. Frames involved in any collision are not counted nor are frames that experienced a transmit underrun.
