PCMCIA Fast Ethernet MAC Controller
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.
