BITS
0
Flow Control on Any Frame (FCANY). When this bit is set, the LAN9215i
will assert back pressure, or transmit a pause frame when the AFC level is
reached and any frame is received. Setting this bit enables full-duplex flow
control when the LAN9215i is operating in full-duplex mode.
When this mode is enabled during half-duplex operation, the Flow Controller
does not decode the MAC address and will send a pause frame upon
receipt of a valid preamble (i.e., immediately at the beginning of the next
frame after the RX data FIFO level is reached).
When this mode is enabled during full-duplex operation, the Flow Controller
will immediately instruct the MAC to send a pause frame when the RX data
FIFO level is reached. The MAC will queue the pause frame transmission
for the next available window.
Setting this bit overrides bits [3:1] of this register.
