Function
(EAs)
Moves the source operand contents or immediate data
to CCR or EXR. Although CCR and EXR are 8-bit
registers, word-size transfers are performed between
them and memory. The upper 8 bits are valid.
CCR
Transfers CCR or EXR contents to a general register or
memory. Although CCR and EXR are 8-bit registers,
word-size transfers are performed between them and
memory. The upper 8 bits are valid.
CCR
Logically ANDs the CCR or EXR contents with
immediate data.
CCR
Logically ORs the CCR or EXR contents with immediate
data.
CCR
Logically exclusive-ORs the CCR or EXR contents with
immediate data.
PC + 2
Only increments the program counter.
if R4L
else next;
if R4
else next;
Transfers a data block according to parameters set in
general registers R4L or R4, ER5, and ER6.
R4L or R4: size of block (bytes)
ER5: starting source address
ER6: starting destination address
Execution of the next instruction begins as soon as the
transfer is completed.
