Dual Data Pointer Registers:
To facilitate accessing both internal and external data memory, two banks of 16-bit Data
Pointer Registers are provided: DP0 at SFR address locations 82H-83H and DP1 at 84H-85H. Bit DPS = 0 in SFR AUXR1
selects DP0 and DPS = 1 selects DP1. The user should always initialize the DPS bit to the appropriate value before
accessing the respective Data Pointer Register.
Power Off Flag:
The Power Off Flag (POF) is located at bit 4 (PCON.4) in the PCON SFR. POF is set to “1” during power
up. It can be set and rest under software control and is not affected by reset.
