CHAPTER 3 HOW TO USE MINICUBE2 WITH V850 MICROCONTROLLER

User’s Manual U18371EJ1V0UM

3.2.6 Cautions on debugging

This section describes cautions on performing on-chip debugging for a V850 microcontroller.

Be sure to read the following to use MINICUBE2 properly.

(1) Handling of device that was used for debugging

Do not mount a device that was used for debugging on a mass-produced product, because the flash memory

was rewritten during debugging and the number of rewrites of the flash memory cannot be guaranteed.

Moreover, do not embed the debug monitor program into mass-produced products.

(2) When breaks cannot be executed

Forced breaks cannot be executed 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 UART, and the main clock has been

stopped

(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 UART, and the main clock has been

stopped

• Mode for communication between MINICUBE2 and the target device is UART, 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 CSI-H/S

• Mode for communication between MINICUBE2 and the target device is UART, 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.
