If there is an overflow, bits 32 and later are ignored.
For example, if 1 is added to 11111111111111111111111111111111(−1), it will
become 00000000000000000000000000000000(0).
Stores as 4-byte integer at the write destination address. (−2,147,483,648 to
2,147,483,647 in decimal)
The data format is described below.
The most significant bit is treated as the sign. (0: Positive, 1: Negative)
