These include power-on reset (POR) and power-up clear (PUC) handling, NMI source selection and management, reset interrupt vector generators, bootstrap loader (BSL) entry mechanisms, and configuration management (device descriptors). It also includes a data exchange mechanism when using JTAG that is called a JTAG mailbox and that can be used in the application. Table 13.
