Interrupt Controller (INTC)
MPC5566 Microcontroller Reference Manual, Rev. 2
Freescale Semiconductor 10-9
10.3 Memory Map and Register Definition
Table 10-3 is the INTC memory map.
2
Primary, alternate, or GPIO function. The primary name labels the pin on the PBGA pinout.
3
Terminology is O - output, I - input, Up - weak pullup enabled, Down - weak pulldown enabled, Low - output driven low,
High - output driven high.
4
Function after reset of GPI is general-purpose input.

Address Register Name Register Description Bits
Base (0xFFF4_8000) INTC_MCR INTC module configuration register 32
Base + 0x0004 — Reserved —
Base + 0x0008 INTC_CPR INTC current priority register 32
Base + 0x000C — Reserved —
Base + 0x0010 INTC_IACKR INTC interrupt acknowledge register
