Collision window / Retry register.
RETRANSMAX | RETRANSMISSION MAXIMUM.This is a programmable field specifying the number of retransmission attempts following a collision before aborting the packet due to excessive collisions. The Standard specifies the attemptLimit to be 0xF (15d). See IEEE 802.3/4.2.3.2.5. |
RESERVED | Reserved. Read value is undefined, only zero should be written. |
COLLWIN | COLLISION WINDOW. This is a programmable field representing the slot time or collision window during which collisions occur in properly configured networks. The default value of 0x37 (55d) represents a 56 byte window following the preamble and SFD. |
RESERVED | Reserved. Read value is undefined, only zero should be written. |
