3.3.15.1 REPEAT Loop Construct

The REPEAT instruction causes the instruction that follows it to be repeated a specified number of times. A literal value contained in the instruction, or a value in one of the W registers, can be used to specify the REPEAT count value. The W register option enables the loop count to be a software variable.

An instruction in a REPEAT loop is executed at least once. The number of iterations for a REPEAT loop is the 20-bit literal value + 1 or Wn + 1. The syntax for the two forms is shown in REPEAT Loop Construct.

;	Using a literal value as a counter
REPEAT #lit20	; RCOUNT <-- lit20
(Valid target Instruction)
;
;	Using a W register as a counter
REPEAT Wn	; RCOUNT <-- Wn
(Valid target Instruction)
