PREL IMINARY
Maximum ISA Interface versus Local Bus Interface
The maximum ISA interface alternate functions are configured via the DTR and RTS pin states when the lanSC310
microcontroller is reset.
Notes:
See Table 25 on page 56 for information on required termination for Maximum ISA Bus and Local Bus modes.
