2.12.3.4 Modify the I/O register contents

The I/O register values can be edited.

Select the value of the I/O register to edit in the [Value] area, then click on it again 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.

Caution 1.

This operation cannot be performed during program execution.

Caution 2.

The value of the read-only I/O register cannot be edited.

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.

ASCII characters can be entered to the I/O register value.

-	When the numeric "0x41" is written to the I/O register "OSTMnXX" >> "0x41" is written in the port "OSTMnXX".

-	When the ASCII character "'A'" is written to the I/O register "OSTMnXX" >> "0x41" is written in the port "OSTMnXX".
