DescriptionR/WNameBit(s)
Sleep mode enable. When the MAGIC_ENA bit is 1, set this bit to
1 to put the MAC function to sleep and enable magic packet
detection.
This bit is not available in the small MAC variation.
RWSLEEP20
Node wake-up request. Valid only when the MAGIC_ENA bit is
1.
The MAC function sets this bit to 1 when a magic packet is
detected.
The MAC function clears this bit when the SLEEP bit is set
to 0.
ROWAKEUP21
Pause frame generation. Set this bit to 1 to generate a pause
frame independent of the status of the receive FIFO buffer. The
MAC function sets the pause quanta field in the pause frame
to the value configured in the pause_quant register.
RWXOFF_GEN22
MAC control frame enable on receive.
Set this bit to 1 to accept control frames other than pause
frames (opcode = 0x0001) and forward them to the user
application.
Set this bit to 0 to discard control frames other than pause
frames.
RWCNTL_FRM_ENA23
Payload length check on receive.
Set this bit to 0 to check the actual payload length of receive
frames against the length/type field in receive frames.
Set this bit to 1 to omit length checking.
This bit is not available in the small MAC variation
RWNO_LGTH_CHECK24
10-Mbps interface enable. Set this bit to 1 to enable the 10-Mbps
interface. The MAC function asserts the ena_10 signal when
you enable the 10-Mbps interface. You can also enable the 10-
Mbps interface by asserting the set_10 signal.
RWENA_1025
Erroneous frames processing on receive.
Set this bit to 1 to discard erroneous frames received. This
applies only when you enable store and forward operation
in the receive FIFO buffer by setting the rx_section_full
register to 0.
Set this bit to 0 to forward erroneous frames to the user
application with rx_err[0] asserted.
RWRX_ERR_DISC26
Set this bit to 1 to disable MAC configuration register read
timeout.
