Control register direct
32-bit register direct
The 32-bit concatenated register content of two
specified registers is the object of the operation.
This addressing mode can be used with the
SHL, SHA, JMPI, and JSRI instructions.
Valid register and instruction combinations
are as follows.
R2R0, R3R1
A1A0
The specified control register is the
object of the operation.
This addressing mode can be used
with the LDC, STC, PUSHC, and
POPC instructions.
If SP is specified, the stack pointer
indicated by the U flag is the object of
the operation.
