2.4I/O Configuration

The cPB-4612 addresses up to 64 KB of I/O using a 16-bit I/O address. The cPB-4612 is populated with many commonly used I/O peripheral devices. The I/O address location for each peripheral is shown in the "I/O Address Map" illustration.

I/O Address Map

*Onboard ISA peripherals addressed between

100h - 7FFh decode 11 bits of address (A0h - A10h). Therefore, these peripherals will alias throughout the 16-bit I/O space at the following ranges:

x100-x3FFh

x500-x7FFh

x900-xBFFh xD00-xFFFh

PCI devices can fully utilize the address space from

D00 - FFFFh, since subtractive decoding is used for the onboard ISA devices.
