3.17. JMP
- 41 -
Instruction: JMP @A + DPTR
Function: Jump indirect
Description:
Add the eight-bit unsigned contents of the accumulator with the sixteen-
bit data pointer, and load the resulting sum to the program counter. This
will be the address for subsequent instruction fetches. Sixteen-bit
addition is performed (modulo 2 16): a carry-out from the low-order
eight bits propagates through the higher-order bits. Neither the
accumulator nor the data pointer is altered. No flags are affected.
Operation: (PC) ← (A) + (DPTR)
