3.4.1
The DSP instructions 10 general registers in the 16 general registers as address pointers or index
registers for double data transfers and single data transfers. In the following descriptions, another
register function in the DSP instructions is also indicated within parentheses [ ].
• Double data transfer instructions (X memory and Y memory are accessed simultaneously)
• Single data transfer instructions
X memory (MOVX.W)
Y memory (MOVY.W)
Any logical space (MOVS.W/L)
In double data transfers, X memory Y memory can be accessed simultaneously. To specify X
and Y memory addresses, two address pointers are supported.
In single data transfer, any logical address space can be accessed via the L bus. The following
address pointers and index registers are used.
