Interrupt register description

7.5.1

CPU CC register interrupt bits

These two bits indicate the current interrupt software priority (see Table 18) and are

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 Table 20: Interrupt dedicated instruction set).
