Status bit
Set the M0M1MAP status bit, configuring the mapping of the M0 and M1
memory blocks for C28x/C2XLP operation. The memory blocks are
mapped as follows:
Data Space
M0: 0x000 to 0x3FF
M1: 0x400 to 0x7FF
The M0M1MAP bit is set.
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
