12.3.1.3
One multiply and two divide instructions are provided. The 8-bit by 8-bit multiply instruction (MUL)
produces a 16-bit result. The integer divide (IDIV) performs a 16-bit by 16-bit divide and produces
a 16-bit result and a 16-bit remainder. The fractional divide (FDIV) divides a 16-bit numerator by a
larger 16-bit denominator to produce a 16-bit result (a binary weighted fraction between 0 and
0.99998) and a 16-bit remainder. FDIV can be used to further resolve the remainder from an IDIV
or FDIV operation.
12.3.1.4
This group of instructions is used to perform the boolean logical operations AND, inclusive-OR,
exclusive-OR, and complement.
