4.11.1
The SL11R allocates addresses from 0x0000 to 0x003E for hardware interrupts. The hardware interrupt vectors are shown below:
Table 4-3. Hardware Interrupt Table
Notes:
All these vector interrupts are read/write accessible. You can overwrite these default software interrupt vectors by replacing your
interrupt service subroutine.
The addresses from 0x0000 to 0x003E are read/write accessible and can be used for variables.
4.11.2
This is a global hardware interrupt enable register that allows control of the hardware interrupt vectors. The SL11R BIOS default
set-up of this register is 0x28 (i.e. USB and UART bits are set).

5.
These hardware interrupt vectors are reserved for internal SL11R-BIOS usage. You should not attempt to overwrite these functions.
These hardware interrupt vectors are initialized to return on the interrupt.
The SOF interrupt is generated when there is an incoming SOF on the USB.
