3.17. JMP
Instruction:
Function:
JMP @A + DPTR
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:
