The PERIPHID3 Register characteristics are:
Part of the set of Peripheral Identification registers. Contains the RevAnd and Customer Modified fields.
Present in all configurations.
Figure 3.46 shows the PERIPHID3 Register bit assignments.
Table 3.47 shows the PERIPHID3 Register bit assignments.
If the component is reusable IP, this value indicates whether the customer has modified the behavior of the component. In most cases, this field is zero.
This field indicates the minor errata fixes specific to this design. For example, metal fixes after implementation. In most cases, this field is zero. It is recommended that the component designer ensures that the metal fix changes this field, if required. For example, by driving it from registers that reset to zero.
