above conditions
#BMR ... Cancels condition set by BM command
#BM
PC ----:
... Entering after canceling BM setting confirms cancellation
#
(1) Use of the BM command automatically cancels BA, BD and BR commands.
(2) This instruction runs a break comparison only during execution with memory access. The
above described limitations remain even when ADDR, data and R/W are masked.
Therefore, a break will not occur when the instruction does not access data memory even
if the PC and register values coincide.
(3) Each model has a different RAM area, and XY settings in a BM command can be set to
FFF.
