table is located at address 0x0000_0000 in the code space. By setting the Vector Table Offset Register,
you can place the vector table at any address in the code or SRAM space.
When an exception occurs, the CPU suspends the currently executing process and branches to the
When the CPU detects an exception, it pushes the contents of the following eight registers to the stack
The SP is decremented by eight words by the completion of the stack push. The following shows the
The CPU enables instruction to fetch the interrupt processing with data store to the register.
Prepare a vector table containing the top addresses of ISRs for each exception. After reset, the vector
The vector table should also contain the initial value of the main stack.
