Memory Window Mapping (Example)
The above addresses (to each window) are set by the following registers:
System Memory Address # Mapping Start Low Byte register
System Memory Address # Mapping Start High Byte register
System Memory Address # Mapping Stop Low Byte register
System Memory Address # Mapping Stop High Byte register
Card Memory Offset Address # Low Byte register
Card Memory Offset Address # High Byte register
Up to 16MB can be allocated to a signal Memory Address Mapping window.
The window size is assigned by 4KB units.
Five windows can be allocated to each slot.
Each window is enabled by setting the following register:
Address Window Enable register (+06h or +46h)
The MSM60804 supports both 8-bit and 16-bit accessing modes on both systems
interface and card interface sides.
On the system interface side, the 8-bit and 16-bit accessing modes are switched by
the SBHE signal.
On the card interface side, the accessing method is determined by combinations of
CE1 and CE2 signals.
The values of CE1 and CE2 signals are set by A0 and the System Memory Address
# Mapping Start High Byte register.
