Low-Power Interrupt Control Register (LPICR)
Implementation of low-power stop mode and exit from a low-power mode via an interrupt require
communication between the CPU and logic associated with the interrupt controller. The LPICR is an 8-bit
register that enables entry into low-power stop mode, and includes the setting of the interrupt level needed
to exit a low-power mode.
