DESCRIPTION
The SGS-THOMSON Microelectronics TS75C96
chip set is a highly integrated modem engine, which
can operate in full duplex from 9600 to 300bps. The
modem hardware consists of three analog front
end (MAFE) chips, three DSP processor chips and
additionalmemory chips plus the V.14 serial output
converter.The three SGS-THOMSON analog front
end chips (TS68950/1/2)are the transmit interface,
the receive interface and the clock generator re-
spectively.The modem signal processing functions
are implemented on three ST18930 programmable
digital signal processors.

Description
System Data Bus : these lines are used for data transfer between the
TS75C96 mailbox and the host processor
Chip Select : this input is asserted when the TSC75C96 is to be accessed by
the host processor
Register Select : this signal is used to control the data transfers between the
host processor and the TS75C96 mailbox
System Data Strobe : synchronizes the transfer between the TS75C96
mailbox and the host processor
System Read/Write : control signal for the TSC75C96 mailbox operation
Interrupt Request : signal sent to the host processor to access the TS75C96
mailbox
