3.2.1
The rapid GPIO module is mapped into a 16-byte area starting at location 0xC0_0000. Its memory map is
shown below in
3.2.2
The V1 ColdFire interrupt controller (CF1_INTC) register map is sparsely-populated, but retains
compatibility with earlier ColdFire interrupt controller definitions. The CF1_INTC occupies the upper
64 bytes of the 4 GB address space and all memory locations are accessed as 8-bit (byte) operands.
