Software interrupt priority
CPU CC register interrupt bits description
These two bits indicate the current interrupt software priority:
10: Interrupt software priority = level 0 (main)
01: Interrupt software priority = level 1
00: Interrupt software priority = level 2
11: Interrupt software priority = level 3 (interrupt disable)
These 2 bits 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
