Figure 21. Nested interrupt management
Interrupt registers
CPU CC register interrupt bits
Table 15.
Table 16.
1. TRAP and RESET events can interrupt a level 3 program.
These two bits indicate the current interrupt software priority (see
set/cleared by hardware when entering in interrupt. The loaded value is given by the
corresponding bits in the interrupt software priority registers (ISPRx).
They can be also set/cleared by software with the RIM, SIM, HALT, WFI, IRET and
PUSH/POP instructions (see
