(at F0H) also bit addressable and used along with the accumulator for multiply & divide
operations. E.g., MUL A B instruction multiplies the 8-bit unsigned values in A & B and leaves the 16-bit result in A
(low-byte) & B (high-byte) E.g., DIV A B instruction
divides A by B leaving the integer result in A and
remainder in B.
Pointer) (at 81H) is an 8-bit register contains the address of the data item currently on the top of stack.
Its operations include “Pushing” &
“Popping” data from the stack.
Pointer) is 16-bit register at 82H (DPL, low-byte) and 83H (DPH, high-byte) used to access external
code or data memory. It can be specified
by its 16-bit name, DPTR, or by each
individual byte name, DPH and DPL.
