Frank,
get the datasheet and application notes from SMSC.
The ISA interface is your reference.
For smooth operation with the C16x MCU you will need to connect: D0 - D15 A0 thru A9 CE1 / A19 to VCC AEN to any free C167 Chipselect (example CS# 3) ALE to BALE BHE# to SBHE/CE2 RD# to IORD/xDS WR# to IOWR EN16 to GND
INTR0 to any Interrupt/CAPCOM line. Note: the SMSC interrupt is a level interrupt. with the CAPCOM pins you may only detect rising edge. Since the SMSC has a neat MMU and sufficient buffer space you can poll it.
Consider using the 16 bit mode.
Set ADDRSELx according to your I/O address selection and add 0x300, also configure BUSCONx (try 0x68E)
regards /jan
