System Module (SYS) (Link to User's Guide)

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, bootstrap

loader entry mechanisms, as well as configuration management (device descriptors). It also includes a data

exchange mechanism via JTAG called a JTAG mailbox that can be used in the application.
