- Subject: [ECOS] mips interrupt question
Hi all -
I was looking through the interrupt handling stuff and the hal_vsr_table
defined in hal/mips/arch/v2_0/src/vectors.S looks 2x too large (64
entries vs. 32)
to me.
The indexes into the table are generated by adding a 7 bit field in from
the
cause register to the base of the table. Is there some other use of the
extra
32 entries that I'm missing or a variant that uses bit 7 of the cause
register
to index more entries?
