Q
What is the difference between the DIV instruction and the DIVX instruction?
Either of the DIV instruction and the DIVX instruction is an instruction for signed division,
the sign of the remainder is different.
The sign of the remainder left after the DIV instruction is the same as that of the dividend, on
the contrary, the sign of the remainder of the DIVX instruction is the same as that of the
divider.
In general, the following relation among quotient, divider, dividend, and remainder holds.
dividend = divider
Since the sign of the remainder is different between these instructions, the quotient ob-
tained either by dividing a positive integer by a negative integer or by dividing a negative
integer by a positive integer using the DIV instruction is different from that obtained using
the DIVX instruction.
For example, dividing 10 by –3 using the DIV instruction yields –3 and leaves +1, while doing
the same using the DIVX instruction yields –4 and leaves –2.
Dividing –10 by +3 using the DIV instruction yields –3 and leaves –1, while doing the same
using the DIVX instruction yields –4 and leaves +2.
It is possible to change the value of the interrupt table register (INTB) while a program is
being executed?
Yes. But there can be a chance that the MCU runs away out of control if an interrupt request
occurs in changing the value of INTB. So it is not recommended to frequently change the
value of INTB while a program is being executed.
