The SYS module handles many of the system functions within the device. These features include power-on reset (POR) and power-up clear (PUC) handling, NMI source selection and management, reset interrupt vector generators, bootloader entry mechanisms, and configuration management (device descriptors). The SYS module also includes a data exchange mechanism through SBW called a JTAG mailbox mail box that can be used in the application. Table 9-10 summarizes the interrupts that are managed by the SYS module.
