Chapter 4 Memory

to disengage security is by mass-erasing the flash (normally through the background debug interface) and verifying the flash is blank.

4.2.2ColdFire Rapid GPIO Memory Map

The rapid GPIO module is mapped into a 16-byte area starting at location 0x(00)C0_0000. Its memory map is shown below in Table 4-6.

4.2.3ColdFire Interrupt Controller Memory Map

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 device memory map and all memory locations are accessed as 8-bit (byte) operands.
