The problem is that after I use commands:
set the T0 priority to 1 and T1 priority to 2, then I read the Vested Vector Interrupt in IAR6.40 .2. I found it set T0's priority to 2.
In this table, the T0 and T1 is IRQ 12, 13 not corresponding to the manual said IRQ11 and 12.
Any suggestion about this?
