Exceptions
In addition, two weak general exception handlers are provided that can be overridden
by the application — one to handle exceptions when StatusBEV is 1
(_bootstrap_exception_handler), and one to handle exceptions when
StatusBEV
by the application — one to handle exceptions when StatusBEV is 1
(_bootstrap_exception_handler), and one to handle exceptions when
StatusBEV
is 0 (_general_exception_handler). Both the weak Reset exception
handler and the weak general exception handler provided with the start-up code enters
an infinite loop. The start-up code arranges for a jump to the reset exception handler to
be located at 0xBFC00380, and a jump to the general exception handler to be located
at EBASE + 0x180.
an infinite loop. The start-up code arranges for a jump to the reset exception handler to
be located at 0xBFC00380, and a jump to the general exception handler to be located
at EBASE + 0x180.
Both handlers must be attributed with the nomips16 [e.g., __attribute__
((nomips16))
((nomips16))
], since the start-up code jumps to these functions.
