BM, BMR
SET/RESET BREAK MULTIPLE CONDITION
#BM (With guidance)
#BMR
Sets the compound break function for multiple breaks when all conditions for the evaluation
board CPU PC, data RAM access, and register values coincide.
(1) Although the BA, BD and BR conditions can be set independently, the BM command
generates a break when all conditions for the PC, data RAM access, and register values
coincide. In other words, it can be thought of as the AND setting for the BA, BD and BR
commands.
(2) Previously set BA, BD and BR conditions are canceled by the BM command. Also, the BM
setting is canceled when the BA, BD and/or BR conditions are set after the BM condition
is set.
(3) The BMR command cancels the BM condition.
(4) A break is set at only one point by the BM command. Each register setting can be masked.
