Freescale Semiconductor
NOTE
Vector addresses and their relative interrupt priority are determined at the
MCU level.
27.8.1
Description of Flash Interrupt Operation
The logic used for generating interrupts is shown in Figure 27-32.
The Flash module uses the CBEIF and CCIF flags in combination with the CBIE and CCIE enable bits to
generate the Flash command interrupt request.
Figure 27-32. Flash Interrupt Implementation
For a detailed description of the register bits, refer to Section 27.3.2.4, “Flash Configuration Register
(FCNFG)” and Section 27.3.2.6, “Flash Status Register (FSTAT)” .
