(3) When pseudo real-time RAM monitor (RRM) function and DMM function do not operate
The pseudo RRM function and DMM function do not operate if one of the following conditions is satisfied.
Interrupts are disabled (DI)
Interrupts issued for the serial interface, which is used for communication between MINICUBE2 and the target
device, are masked
Standby mode is entered while standby release by a maskable interrupt is prohibited
Mode for communication between MINICUBE2 and the target device is UARTA0, and the main clock has been
stopped
Mode for communication between MINICUBE2 and the target device is UARTA0, and a clock different from the
one specified in the debugger is used for communication
(4) Standby release with pseudo RRM and DMM functions enabled
The standby mode is released by the pseudo RRM function and DMM function if one of the following conditions is
satisfied.
Mode for communication between MINICUBE2 and the target device is CSIB0 or CSIB3
Mode for communication between MINICUBE2 and the target device is UARTA0, and the main clock has been
supplied.
(5) Writing to peripheral I/O registers that requires a specific sequence, using DMM function
Peripheral I/O registers that requires a specific sequence cannot be written with the DMM function.
(6) Flash self programming
If a space where the debug monitor program is allocated is rewritten by flash self programming, the debugger can
no longer operate normally.
