Explanation of function and operation
1. 16-bit operation (SMOV and SMOVP)
The contents of the transfer source
9999) respectively. "m2" digits starting from the "m1"th digit are transferred to the transfer destination
from the "n"th digit, converted into binary, and then stored to the transfer destination
• While the command input is OFF, the transfer destination
• When the command input turns ON, only the specified digits in the transfer destination

2. Extension function
When M8168 is set to ON first and then SMOV instruction is executed, conversion from binary to BCD is not executed.
Data is moved in units of 4 bits.
