TCMD — Transmit Command
11.3.2.4 Ethertype Control (ETCTL)
Read: Anytime.
Write: Anytime, but the user must not change this field while EMACE is set. Changing values while the
receiver is active will affect the outcome of the Ethertype filter.
If every bit in ETCTL is clear, there is no mask for Ethertype messages so all are received. Conversely, if
any bit in ETCTL is set, Ethertype filtering will occur and will be defined by the configuration bits.
FPET — Programmable Ethertype
Freescale Semiconductor
This is a 2-bit write-only field that can launch three different transmission commands: START,
PAUSE, or ABORT. The START command starts transmission of the frame in the transmit buffer. The
PAUSE command starts transmission of a hardware-generated PAUSE frame. The ABORT command
terminates any current transmission after a bad CRC is appended to the frame currently being
transmitted and MII_TXER is asserted. The ABORT command does not affect any received PAUSE
time out. See
Generated PAUSE Control Frame
If this bit is set, all messages with the Ethertype in ETYPE are accepted. If this bit is clear, messages
of this type are ignored.
1 = Accept Ethertype messages selected in ETYPE.
0 = Ignore Ethertype messages selected in ETYPE.

TCMD
The START and PAUSE commands are ignored if there is a transmission in
progress (TXACT is set). After the reception of a PAUSE frame, a launched
START command is suspended until the pause time has expired. During the
pause time, the EMAC may transmit a control PAUSE frame if no START
transmission is pending.
