Not affected.
Not affected unless the ACUSR is specified as the destination operand.
Effective Address field—Specifies the memory location for the transfer.
register or moves the contents of an access control register to the destination effective
address.
The instruction is a long-word operation for the access control registers (AC0 and
AC1). It is a word operation for the access control unit status register (ACUSR).
Writing to the ACx registers enables or disables the access control register according
to the E-bit written. If the E-bit = 1, the access control register is enabled. If the E-bit =
0, the register is disabled
R/W field—Specifies the direction of transfer.
0—Memory to ACUSR
1—ACUSR to memory
