By default, the processor uses the Low Interrupt Latency (LIL) behaviors introduced in version 6 and later of the ARM Architecture. The processor also has a port for connection of a RM42L432 Hercules ARM Cortex-R4 Microcontrollers normal interrupt can be enabled by clearing the "I" bit of the Current Program Status Register (CPSR) Although it is not the intent of this document to serve as a guide to using Contents. 1.
