Load Data Memory and Increment
Assume that register pair HL contains the address 2FH and internal RAM location 2FH contains the
value 0FH:

LDI
JPS
JPS
The instruction 'JPS XXX' is skipped since an overflow occurred after the 'LDI A,@HL' and the
instruction 'JPS YYY' is executed.
dst,src
The contents of a data memory location are loaded into the accumulator, and the contents of the
register L are incremented by one. If an overflow occurs (e.g., if the resulting value in register L is
0H), the next instruction is skipped. The contents of data memory and the carry flag value are not
affected.
