7.1.6 Maximum Frame Register (MAXF - 0xFFE0 0014)
7.1.7 PHY Support Register (SUPP - 0xFFE0 0018)
7.1.8 Test Register (TEST - 0xFFE0 001C)
The Maximum Frame register (MAXF) has an address of 0xFFE0 0014. Its bit definition is
shown in
The PHY Support register (SUPP) has an address of 0xFFE0 0018. The SUPP register
provides additional control over the RMII interface. The bit definition of this register is
shown in
Unused bits in the PHY support register should be left as zeroes.
The Test register (TEST) has an address of 0xFFE0 001C. The bit definition of this
register is shown in
Function
This field resets to the value 0x0600, which represents a maximum receive frame of
1536 octets. An untagged maximum size Ethernet frame is 1518 octets. A tagged
frame adds four octets for a total of 1522 octets. If a shorter maximum length
restriction is desired, program this 16 bit field.
Unused
Function
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. User software should not write ones to reserved bits. The value read from
a reserved bit is not defined.
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, user software should not write ones to reserved bits. The value read from
a reserved bit is not defined.
Function
Unused
This bit configures the Reduced MII logic for the current operating speed. When set,
100 Mbps mode is selected. When cleared, 10 Mbps mode is selected.
