UT2 register functions, as shown in Table 23-13.
Table 23-13. UT2 Field Descriptions
Field
Description
31-0 Data Array Input. These bits enable checks of ECC logic by allowing data bits to be input into the ECC
DAI[63:32] logic and then read out by doing array reads or array integrity checks. The DAI[63:32] correspond to
the 32 Array bits representing Word 1of the double word selected in the ADR register.
23.1.6.12 User Multiple Input Signature Registers
The Multiple Input Signature Registers (UM0, UM1, UM2, UM3 and UM4) provide a means to evaluate
array integrity.
23.1.6.12.1 UM0 Register
The following field and bit descriptions fully define the UM0 register.
