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

14.34.8.12 SKIP S, C
Function:
Conditional
skip
instruction
Description: If condition C is true then
skip S instructions. The condition C may
be negated (N=1) and is described in the
table below (note same conditions as RPT
C instruction).

Description
CCA is true
Function
CCA=1
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 next instruction. The
condition C may be negated by setting
N=1 and is described in the table below.
