5.3.5
INC (FNC 24)
Operation:
On every execution of the instruction the device
specified as the destination D, has its current value
incremented (increased) by a value of 1.
In 16 bit operation, when +32,767 is reached, the
specified as the destination D, has its current value
incremented (increased) by a value of 1.
In 16 bit operation, when +32,767 is reached, the
next increment will write a value of -32,768 to the destination device.
In 32 bit operation, when +2,147,483,647 is reached the next increment will write a value of -
2,147,483,648 to the destination device.
In both cases there is no additional flag to identify this change in the counted value.
In 32 bit operation, when +2,147,483,647 is reached the next increment will write a value of -
2,147,483,648 to the destination device.
In both cases there is no additional flag to identify this change in the counted value.
5.3.6
DEC (FNC 24)
Operation:
On every execution of the instruction the device
specified as the destination D, has its current value
decremented (decreased) by a value of 1.
In 16 bit operation, when -32,768 is reached the
specified as the destination D, has its current value
decremented (decreased) by a value of 1.
In 16 bit operation, when -32,768 is reached the
next increment will write a value of +32,767 to the destination device.
In 32 bit operation, when -2,147,483,648 is reached the next increment will write a value of
+2,147,483,647 to the destination device.
In both cases there is no additional flag to identify this change in the counted value.
In 32 bit operation, when -2,147,483,648 is reached the next increment will write a value of
+2,147,483,647 to the destination device.
In both cases there is no additional flag to identify this change in the counted value.
