PCMCIA Fast Ethernet MAC Controller
Transmit Clock : this signal is driven by PHY with 20MHz clock.
Transmit Data : STXD is transition synchronously with respect to the
rising edge of STXC. For each STXC period in which STXE is
asserted, STXD is accepted for transmission by the PHY.
Transmit Enable : STXE is transition synchronously with respect to
the rising edge of STXC. STXE indicates that the port is presenting
data on STXD for transmission.
Collision : this signal is driven by PHY when collision is detected.
Receive Clock : SRXC is driven by PHY for received data
synchronization.
Receive Data : SRXD is driven by the PHY synchronously with respect
to SRXC.
Carrier Sense : Asynchronous signal SCRS is asserted by the PHY
when either the transmit or receive medium is non-idle.
Link indicator : Active low indicate the SNI interface is link to
network. When SNI is not used must keep the pin no connection or
pull high the signal.
Modem Ready : MRDY low indicates that modem is initializing the
modem after reset signal asserted or the modem is at SLEEP/STOP
mode.
Modem Reset :This signal asserts low to reset the modem chipset.
Modem Chip Select : This signal connected to modem chip select pin.
Modem Power Down : Rockwell modem chipset, this signal asserts
low to let modem chipset into power down mode. AT&T modem
chipset, this signal asserts high to let modem chipset into power down
mode.
Modem Interrupt : This signal driven by modem chipset to active
interrupt.
Ring Input :This signal is driven by DAA’s ring detect circuit. When
a telephone ringing signal is being received.
Modem Audio : This signal is passed to PCMCIA interface via SPKR.
Read register offset 18h bit 3 value reflects this input value.
Read register offset 18h bit 2 value reflects this input value.
Read register offset 18h bit 1 value reflects this input value.
Read register offset 18h bit 0 value reflects this input value.
