• Description: 16-bit Digital Signal Controllers
• Manufacturer: Freescale Semiconductor, Inc

highest-priority level 2 interrupt, regardless of their location in the interrupt table, prior to being declared
as fast interrupt. Fast interrupt 0 has priority over Fast Interrupt 1. To determine the vector number of each
IRQ, refer to
5.6.13
5.6.13.1
The lower 16 bits of the vector address are used for Fast Interrupt 0. This register is combined with
FIVAH0 to form the 21-bit vector address for Fast Interrupt 0 defined in the FIM0 register.
5.6.14
5.6.14.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.14.2
The upper five bits of the vector address are used for Fast Interrupt 0. This register is combined with
FIVAL0 to form the 21-bit vector address for Fast Interrupt 0 defined in the FIM0 register.
