Data bus to host CPU
Address bus to host CPU
Chip select signal
Interface memory read signal
Interface memory write signal
Interrupt request to host CPU
System reset signal
Timing clock for generating eye pattern data. This may be used as the shift clock for an external shift register.
Eye pattern synchronization signal
Eye pattern data serial outputs (8 bits, MSB first)
Request to send signal. The low level at this pin starts transmission; the high level suspends it.
Clear to send signal. The low level at this pin signals the availability of data for transmission; the high level indicates
that the data is invalid.
Received line signal data signal. The low level at this pin gives the timing for transferring the data received to the
terminal.
