instructions
B/W
(EAs) â CCR, (EAs) â EXR
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.
STC
B/W
CCR â (EAd), EXR â (EAd)
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.
ANDC
B
CCR ⧠#IMM â CCR, EXR ⧠#IMM â EXR
Logically ANDs the CCR or EXR contents with
immediate data.
ORC
B
CCR ⨠#IMM â CCR, EXR ⨠#IMM â EXR
Logically ORs the CCR or EXR contents with immediate
data.
XORC
B
CCR â #IMM â CCR, EXR â #IMM â EXR
Logically exclusive-ORs the CCR or EXR contents with
immediate data.
NOP
â
PC + 2 â PC
Only increments the program counter.

instruction
EEPMOV.B â
if R4L â 0 then
Repeat @ER5+ â @ER6+
R4Lâ1 â R4L
Until R4L = 0
else next;
EEPMOV.W â
if R4 â 0 then
Repeat @ER5+ â @ER6+
R4â1 â R4
Until R4 = 0
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.
Notes: *1 Size refers to the operand size.
B: Byte
W: Word
L: Longword
*2 When using the TAS instruction, use register ER0, ER1, ER4, or ER5.
