2.11.3.4 Changing the contents of I/O registers

The I/O register values can be edited.

In the [Value] area, click the selected I/O register value again to set it in the Edit mode (Pressing the [Esc] key cancels the edit mode).

Edit the value directly from the keyboard and then press the [Enter] key. The value you've changed is written into the debug tool's target memory.

Caution 1.

This operation cannot be performed during program execution.

Caution 2.

The values of read-only I/O registers cannot be changed.

Remark 1.

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

Remark 2.

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

Remark 3.

I/O register values can also be entered using ASCII characters.

-	When "0x41" is entered as the value of I/O register “CRC.CRCDOR” >> "0x41" is written to "CRC.CRCDOR".

-	When ASCII character "'A'" is entered as the value of I/O register “CRC.CRCDOR“ >> "0x41" is written to "CRC.CRCDOR".
