Re: 91c96 with Infineon C16x
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)
