Description The ++BL(595) instruction adds 1 to the 8-digit BCD content of Wd+1 and
Wd. The content of the specified words will be incremented by 1 every cycle
as long as the execution condition of ++BL(595) is ON. When the up-differen-
tiated variation of this instruction (@++BL(595)) is used, the content of the
++BL(595)
