4.3 Memory Map
The AM4011 board uses the standard AT ISA memory map.
4.3.1 I/O Address Map
The following table sets out the AM4011-specific I/O registers. The blue shaded table cells
indicate MMC-specific registers.
4.4 AM4011-Specific Registers
The following registers are special registers which the AM4011 uses to watch the onboard
hardware special features and the AMC control signals.
Normally, only the system BIOS uses these registers, but they are documented here for
application use as required.
