The following notations are used in this section. In the operand syntax state-
ments of the instruction definitions, the operand on the right is the destination
operand.
An = any address register, A7-AO
On = any data register, 07-00
Rn = any
addr~ss
or data register
CCR = condition code register (lower byte of status register)
cc = condition codes from CCR
SR = status register
SP = active stack pointer
USP = user stack pointer
ISP = supervisor/interrupt stack pointer
MSP = supervisor/master stack pointer
SSP = supervisor (master or interrupt) stack pointer
OFC = destination function code register
SFC = source function code register
Rc = control register (VBR, SFC, OFC, CACR)
MRc = MMU control register (SRP, URP, TC, OTTO, OTT1, ITTO,
IIT1, MMUSR)
MMUSR = MMU status register
B, W, L = specifies a signed integer data type (twos complement)
of byte, word, or long word
S = single-precision real data format (32 bits)
0= double-precision real data format (64 bits)
X = extended-precision real data format (96 bits, 16 bits
unused)
P = packed BCD real data format (96 bits, 12 bytes)
FPm, FPn = any floating-point data register, FP7-FPO
PFcr = floating-point system control register (FPCR, FPSR, or
FPIAR)
k = a twos-complement signed integer (- 64 to
+
17) that
specifies the format of a number to be stored in the packed
BCD format
d = displacement; d16 is a 16-bit displacement
<ea> = effective address
list = list of registers, for example 03-00
#<data> = immediate data; a literal integer
{offset:width} = bit field selection
MOTOROLA
label = assemble program label
[m] = bit m of an operand
[m: n] = bits m through n of operand
