PRODUCTION DATA.
The SYS module handles many of the system functions within the device. These system functions include power-on reset and power-up clear 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 JTAG called a JTAG mailbox that can be used in the application. Table 6-10 lists the interrupt vector registers of the SYS module.
