• Manufacturer Part Number: mc56f8335
• Description: 16-bit Digital Signal Controller
• Manufacturer: Freescale Semiconductor, Inc

5.6.17.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.17.2
The upper five bits of the vector address are used for Fast Interrupt 1. This register is combined with
FIVAL1 to form the 21-bit vector address for Fast Interrupt 1 defined in the FIM1 register.
5.6.18
5.6.18.1
This register combines with the other five to represent the pending IRQs for interrupt vector numbers 2
through 81.
5.6.18.2
This bit is reserved or not implemented. It is read as 1 and cannot be modified by writing.
5.6.19
5.6.19.1
This register combines with the other five to represent the pending IRQs for interrupt vector numbers 2
through 81.
