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. DMAC access uses
an 8-/16-/32-bit unit. If the I bus accesses X/Y memory simultaneously with an access from the X
bus/Y bus or L bus, the I bus master has a higher priority.
When accessing X/Y memory from the DMAC, use physical addresses in the range H'05000000 to
H'05FFFFFF.
