Hex Code in:
Binary Mode = [A5][Encoding]

Operation:
DIV (8-bit operands)
(Rmd) ← remainder (Rmd) / (Rms) if <dest> md = 0,2,4,..,14
(Rmd+1) ← quotient (Rmd) / (Rms)
(Rmd–1) ← remainder (Rmd) / (Rms) if <dest> md = 1,3,5,..,15
(Rmd) ← quotient (Rmd) / (Rms)

Hex Code in:
Binary Mode = [A5][Encoding]
Source Mode = [Encoding]
Operation:
DIV (16-bit operands)
(WRjd) ← remainder (WRjd) / (WRjs) if <dest> jd = 0, 4, 8, ... 28
(WRjd+2) ← quotient (WRjd) / (WRjs)
(WRjd–2) ← remainder (WRjd) / (WRjs) if <dest> jd = 2, 6, 10, ... 30
(WRjd) ← quotient (WRjd) / (WRjs)
For word operands (<dest>,<src> = WRjd,WRjs) the 16-bit quotient is in WR(jd+2), and the
16-bit remainder is in WRjd. For example, for a destination register WR4, assume the
quotient is 1122H and the remainder is 3344H. Then, the results are stored in these register

DIV AB
Function:
Divide
Description:
Divides the unsigned 8-bit integer in the accumulator by the unsigned 8-bit integer in register
B. The accumulator receives the integer part of the quotient; register B receives the integer
remainder. The CY and OV flags are cleared.
