interrupts
The TMS370 family software-programmable interrupt structure permits flexible on-chip and external interrupt
configurations to meet real-time interrupt-driven application requirements. The hardware interrupt structure
incorporates two priority levels as shown in Figure 5. Interrupt level 1 has a higher priority than interrupt
level 2. The two priority levels can be masked independently by the global interrupt mask bits (IE1 and IE2) of
the ST.

Figure 5. Interrupt Control
Each system interrupt is configured independently to either the high- or low-priority chain by the application
program during system initialization. Within each interrupt chain, the interrupt priority is fixed by the position of
the system interrupt. However, since each system interrupt is selectively configured on either the high- or
low-priority-interrupt chain, the application program can elevate any system interrupt to the highest priority.
Arbitration between the two priority levels is performed within the CPU. Arbitration within each of the priority
