and therefore no transmissions
are attempted. DTX = “0”, will set
TXON bit (CSR0 bit 4) if STRT
(CSR0 bit 1) is asserted.
Read/write accessible only when
STOP bit is set.
Disable Receiver results in
PCnet-PCI controller not access-
ing the Receive Descriptor Ring
and therefore all receive frame
data are ignored. DRX = “0”, will
set RXON bit (CSR0 bit 5) if
STRT (CSR0 bit 1) is asserted.
Read/write accessible only when
STOP bit is set.
