Bits 0 to 3: Chip Revision Bits (ID0 to ID3). The lower four bits of the IDR are used to display the die revision of the chip.
ID0 is the LSB of a decimal code that represents the chip revision.
Bits 4 to 7: Device ID (ID4 to ID7). The upper four bits of the IDR are used to display the DS26502 ID. The DS26502 ID is
0000.
