5) RAM monitor   

When using RAM monitor, a User Program execution is stopped temporarily. 

6) Register reference 

When using register reference, a User Program execution is stopped temporarily 

and the data of CPU register and SFR is transferred. 

7) User Program stop 

A User Program stops, a monitor program operates and it waits for next command. 

1) Real time 

When opening a RAM monitor window, a User Program execution is stopped 

temporarily, RAM is read out and the communication is performed. Since a User 

Program is stopped, User Program execution time is prolonged. 

2) Reset vector table 

A reset vector is rewritten at the routine address which is used for a monitor program, 

therefore when referring this area by dump, the value is differenet from the value 

which a user sets. 

3) Interrupt 

Interrupts of Address Match interrupt and Single Step interrupt and BRK instruction 

interrupt and DBC interrupt are used by a monitor program, therefore do not use 

these interrupts in a User Program. 

4) Values after reset 

When a microcomputer is reset, a monitor program is operated, therefore when a 

program is stopped at the head of a User Program, the CPU register and the SFR 

value may differ from the initial value (value after reset) of a microcomputer.
