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, boot strap

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.
