|
asr rp; asr t
|
asrt rp
|
cmp8 rp
|
Bitwise AND of register value and t, placed into t.
|
Arithmetic shift right of a register value into t and the register, or just
t - note that arithmetic shifting preserves the sign.
|
Shift the register value right 't' times; that is, the
number of times indicated by the t register.
|
Compare only bottom 8 bits of t register and a register specified by RPTR.
|
cmp16
|
lsl rp; lsl t
|
lslt rp
|
lsr rp; lsr t
|
Compare only bottom 16 bits of t register and a register specified by RPTR.
|
Logical shift left the register value pointer to by RPTR or t.
|
Logical barrel shift left, using the t register to determine how many
shifts performed.
|
Logical shift right a register or t.
|
lsrt rp
|
not rp; not t
|
or rp
|
rol t
|
Logical barrel shift right, using t for the shift count.
|
Invert the value in the specified register or t.
|
Bitwise OR the value in the specified register with t.
|
Rotate left the t register's value.
|
ror t
|
xor rp
|
zcmp8 rp
|
zcmp16 rp
|
Rotate right the value in t.
|
EXCLUSIVE-OR the specified register with t, and place in t.
|
Compare the lower 8 bits of the specified register with zero.
|
Compare the lower 16 bits of the specified register with zero.
|
zx8 rp; zx8 t
|
zx16 rp; zx16 t
|
|
|
Zero extend the specified register or t after 8 bits - in
other words, the top three bytes of the register are filled with zero.
|
Zero extend the specified register or t after 16 bits -
in other words, the top two bytes of the register are filled with zero.
