14.34.8.10

LABEL

Function:

Set loop label

Description:

Sets next instruction as

start of loop. If the current instruction is the

last instruction in the instruction memory

then the current PC is set as start of loop.

Only one level of loops is supported.

Operation:

LABEL := PC+1

Opcode:

14.34.8.11

RPT C

Function:

Conditional repeat

Description:

If condition C is true then

jump to instruction defined by last LABEL

instruction, i.e. jump to start of loop. If the

condition is false or if a LABEL instruction

has not been executed, then execution will

continue

from

instruction.

The

condition C may be negated by setting

N=1 and is described in the table below.

SKIP S, C

Function:

Conditional

instruction

Description:

If condition C is true then

skip S instructions. The condition C may
