Section 6 X/Y Memory
6.3
The X/Y memory can be accessed by the DSP through the X bus and Y bus. Accesses via the X
bus/Y bus are always 16-bit, while accesses via the L bus are either 16-bit or 32-bit. Accesses via
the X bus and Y bus cannot be specified simultaneously.
6.4
The X/Y memory also exists on the I bus and can be accessed by the DMAC. The DMAC access
is 8-/16-/32-bit unit. If the I bus accesses X/Y memory simultaneously with an access from X
bus/Y bus or L bus, the I bus master has a higher priority.
To access the X/Y memory by the DMAC, the physical address from H’05000000 to H’0501FFFF
should be used.
