[Short break] group box Enables or disables memory access during user program

execution.

Disable: Disables memory access during user program

execution.

Enable: Enables memory access during user program

execution.

Notes: 1. Includes interrupts in a break.

2. When Step Over is performed after selecting [No Programming of the flash memory]

for [Step Over option], the instruction that follows a JSR, BSR, or TRAPA instruction

will also be executed. If there are consecutive JSR, BSR, or TRAPA instructions,

execution proceeds until it reaches an instruction that is not JSR, BSR, or TRAPA.

(When there are consecutive function calls in C language, the program steps all of

these functions.)

MCU to be selected as shown in table 5.3. Note that, however, an error will not be displayed

even if a program which is larger than the internal ROM capacity is downloaded.
