Description
Data pointer high byte
This is the high byte of 16-bit data pointer. DPH combined with DPL serve as a
16-bit data pointer DPTR to address non-scratch-pad memory or Program
Memory. DPS (DPS.0) bit decides which data pointer, DPTR or DPTR1, is
activated.

0 = Data pointer 0 (DPTR) is active by default.
1 = Data pointer 1 (DPTR1) is active.
After DPS switches the activated data pointer, the previous inactivated data
pointer remains its original value unchanged.
27.2 96-Bit Unique Code
Before shipping out, each N76E885 chip was factory pre-programmed with a 96-bit width serial number, which is
guaranteed to be unique. The serial number is called Unique Code. The user can read the Unique Code only by
IAP command. Please see Section 22.1 “IAP Commands” on page 149.
