Note: This instruction is an alias for the “CLRC M0M1MAP” operation.
Operands None
Description Clear the M0M1MAP status bit, configuring the mapping of the M0 and M1
memory blocks for C27x object-compatible operation. The memory blocks
are mapped as follows:
M0 M0
M1
C28 at Reset
(M0M1MAP = 1)

The M0M1MAP bit is cleared.
Repeat This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
Example
; Set the device mode from reset to C27x object-compatible mode:
Reset:
C27OBJ ; Enable C27x Object Mode
C28ADDR ; Enable C27x/C28x Address Mode
.c28_amode ; Tell assembler we are using C27x/C28x addressing
C27MAP ; Enable C27x Mapping Of M0 and M1 blocks
