9 - Miscellaneous Instructions
This final group are the instructions that don't
fit neatly into any other category, which I suppose
makes them a category all their own:
clrf t
|
nop
|
rbnk 0; rbnk 1; rbnk 2
|
rptr rN
|
Clear status bits using the t register value
- all zero bits in the t register clear
the corresponding bits in the status register,
while zero bits in t leave the
status bits unchanged.
|
No operation.
|
Select bank for future register operations.
|
Set index value in RPTR (used for subsequent register indexing).
|
rti
|
rts
|
setf t
|
trap
|
Return from interrupt.
|
Return from subroutine.
|
Set status bits using the t register
value - all one bits in the t register set
the corresponding bits in the status register,
while zero bits in t leave the
status bits unchanged.
|
Enable software interrupt.
