2.10.6.6 Modify the contents of watch-expressions

The values of watch-expressions can be edited.

Double-click the value of the watch-expression to edit in the [Value] area to switch the value to edit mode (press the [Esc] key to cancel the edit mode).

To write the edited value to the target memory, directly enter the value from the keyboard then press the [Enter] key.

Note that only those values that correspond one by one to variables of C language, CPU registers, SFR or assembler symbols can be edited. In addition, read-only SFR values cannot be edited.

This operation can be taken place while the program is in execution. See "2.10.1.4 Display/modify the memory contents during program execution" for details on how to operate it.

Remark 1.

If a number with fewer digits than the size of the variable is entered, the higher-order digits will be padded with zeroes.

Remark 2.

If a number with more digits than the size of the variable is entered, the higher-order digits will be masked.

Remark 3.

If the display format of a character array (type char or unsigned char) is set to ASCII, then the value can also be entered as a string (ASCII/Shift_JIS/EUC-JP/Unicode (UTF-8/UTF-16 Big-Endian/UTF-16 Little-Endian/UTF-32 Big-Endian/UTF-32 Little-Endian)).

Remark 4.

ASCII characters can be entered to values of watch-expressions.

-	Entering via an ASCII character In the [Value] area for the variable "ch", enter "'A'" >> "0x41" will be written to the memory area allocated to "ch"

-	Entering via a numeric value In the [Value] area for the variable "ch", enter "0x41" >> "0x41" will be written to the memory area allocated to "ch"

-	Entering via an ASCII string Set the display format of character array "str" to ASCII, and in the [Value] area, enter ""ABC"" >> "0x41, 0x42, 0x43, 0x00" will be written to the memory area allocated to "str"
