7.1.10 MII Mgmt Command Register (MCMD - 0xFFE0 0024)
7.1.9 MII Mgmt Configuration Register (MCFG - 0xFFE0 0020)
The MII Mgmt Configuration register (MCFG) has an address of 0xFFE0 0020. The bit
definition of this register is shown in
The MII Mgmt Command register (MCMD) has an address of 0xFFE0 0024. The bit
definition of this register is shown in
Function
This bit reduces the effective PAUSE quanta from 64 byte-times to 1 byte-time.
This bit causes the MAC Control sublayer to inhibit transmissions, just as if a
PAUSE Receive Control frame with a nonzero pause time parameter was received.
Setting this bit will cause the MAC to assert backpressure on the link. Backpressure
causes preamble to be transmitted, raising carrier sense. A transmit packet from the
system will be sent during backpressure.
Unused
Function
Set this bit to cause the MII Management hardware to perform read cycles across a
range of PHYs. When set, the MII Management hardware will perform read cycles
from address 1 through the value set in PHY ADDRESS[4:0]. Clear this bit to allow
continuous reads of the same PHY.
Set this bit to cause the MII Management hardware to perform read/write cycles
without the 32 bit preamble field. Clear this bit to cause normal cycles to be
performed. Some PHYs support suppressed preamble.
This field is used by the clock divide logic in creating the MII Management Clock
(MDC) which IEEE 802.3u defines to be no faster than 2.5 MHz. Some PHYs
support clock rates up to 12.5 MHz, however. Refer to
definition of values for this field.
Unused
This bit resets the MII Management hardware.
