Chip ID
DESCRIPTION
Not Used
Pointer that selects a pair of characters from the Chip Identification, where the Chip Identification is a
string of 16 ASCII characters. The ChipID field provides access to the selected character pair. For
example, if the Chip Identification is the first 16 letters of the alphabet,—“ABCD…P”—then setting
ID_Index = PAIR_0, selects the left-most pair, AB, which can be accessed by reading the ChipID field.
Setting ID_Index = PAIR_1, selects the pair, CD.

011 - Pair 3

111 - Pair 7
Not Used
Control bit that resets the entire chip except the Processor Interface (PI) block. Identical to asserting
RESET, except:
(1) it does not reset the control fields, ID Index, Hard Reset, Soft Reset, and Chip ID.
(2) it does not reset the PI Controller in the PI block.
0 - Reset not active (default).
1 - Reset is active for the entire chip except the PI block.
Not Used.
Control bit that is identical to Hard Reset except that it does not reset any control registers.
0 - Reset not active (default).
1 - Reset is active for the entire chip except the PI block and all control registers.
TABLE 4. CHIP ID
TYPE: GLOBAL: ADDRESS: 0x01
DESCRIPTION
Pair of ASCII character codes for the Chip Identification, where the Chip Identification is a string of 16
ASCII characters. The ChipID field provides access to the characters selected by ID_Index. From the
example in the ID_Index description, reading ChipID with ID_Index = PAIR_0 returns the ASCII code for
“AB”. The ASCII code for “A” is 0x41, and the ASCII code for “B” is 0x42; therefore, ChipID would have
the value 0x4142.
