Divide by Top of Stack (DIVS)
Divide Top of Stack is a 32-bit instruction that divides the
8-digit BCD value in the accumulator by a 4-digit BCD
value in the first level of the accumulator stack. The result
resides in the accumulator and the remainder resides in the
first level of the accumulator stack.
NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the Load instruction loads the value in V1400 into
the accumulator. The value in V1420 is loaded into the accumulator using the Load Double
instruction, pushing the value previously loaded in the accumulator onto the accumulator
stack. The BCD value in the accumulator is divided by the BCD value in the first level of the
accumulator stack using the Divide Stack instruction. The Out Double instruction copies the
value in the accumulator to V1500 and V1501.

Discrete Bit Flags Description
SP53 On when the value of the operand is larger than the accumulator can work with.
SP63 On when the result of the instruction causes the value in the accumulator to be zero.
SP70 On anytime the value in the accumulator is negative.
SP75 On when a BCD instruction is executed and a NON-BCD number was encountered.
