(8) Software break (2)
If the debugger does not terminate normally due to a factor such as a freeze while a software break is set, the
instruction for which the software break is set and that has been substituted by a debug instruction remains as
is. To avoid this, select

in the Download dialog box and download the load module. In particular,
take care regarding this point when starting the debugger using a project file, as well as when using PM+.
(9) Caution on performing step execution
Some SFRs (special function registers) remain stopped during step execution. In such a case, execute the
instruction with the real-time execution function.
(10) Cautions when using pseudo real-time RAM monitor function
<1> The user program is stopped while the pseudo real-time RAM monitor function processing is being
performed.
<2> If the pseudo real-time RAM monitor function is executed during a standby state, the standby state is
released.
<3> The program temporarily operates with PCC = 0 during a break. This break time is extended when the
system clock frequency is low or when the CPU operating speed is lowered.
<4> When the pseudo real-time RAM monitor function processing is performed, the IXS value is forcibly set as
shown below, so that the internal low-speed RAM area size becomes the maximum.
Device with OCD control code

V1.xx: 0Ah
Device with OCD control code V2.00 or later: 00h
<5> If the interrupt disabled state (DI setting) is set or the operating clock is switched to internal oscillation
clock

or subclock by the user program during the pseudo real-time RAM monitor function processing,
the pseudo real-time RAM monitor function processing is suspended. A break occurs in the user program,
for approximately 40
µ
s, due to the pseudo real-time RAM monitor function processing.
User program stop period: Approximately 40
