Function
On every execution of the INC instruction, D has its current value incremented by a value of 1.
In 16-bit operation, –32,768 is reached after 32,767 is incremented by a value of 1. In 32-bit operation,
–2,147,483,648 is reached after 2,147,483,647 is incremented by a value of 1.
This instruction does not refresh the zero ag, carry ag, and borrow ag.
Example:
M5
ǒINCP D10Ǔ
The value in D10 is incremented
by 1 each time M5 is set.
