output interrupt or timer OB
processing is disabled.
-- 58 26 Enable interrupt.
This operation cancels the
effect of IA.
-- 49 0,9 Decrement the low byte (bits 0
to 7) of ACCU 1 by the
value n (n=0 to 255).
-- 49 0,9 Increment the low byte (bits 0
to 7) of ACCU 1 by the
value n (n=0 to 255).
-- 252** 188** Process a block.
(Only C DB, JU OB, J U PB,
JU FB, JU SB can be
substituted.)
Actual operands: C DB,
JU OB, JU PB, JU FB, JU SB
