System Module (SYS)
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, and configuration management (device descriptors). SYS also includes a data
exchange mechanism via JTAG called a JTAG mailbox that can be used in the application.
