PRODUCTION DATA
The SYS module handles many of the system functions within the device. These 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). SYS also includes a data exchange mechanism through JTAG called a JTAG mailbox that can be used in the application.
Table 9-11 lists the SYS interrupt vector registers.
