| One time call to enable autovectoring for both USB and FIFO/GPIF. | |
Headerfile for isr.c.
The FX2 has three discrete sets of interrupt vectors. The first set is the standard 8051 vector (13 8-byte entries). The second set is USB interrupt autovector (32 4-byte entries). The third set is the FIFO/GPIF autovector (14 4-byte entries).
Since all the code we're running in the FX2 is ram based, we forego the typical "initialize the interrupt vectors at link time" strategy, in favor of calls at run time that install the correct pointers to functions.
