Each CPU has its own PIE. Both PIEs must be configured independently.
Some interrupts come from shared peripherals that can be owned by either CPU, such as the ADCs and SPIs. These interrupts are sent to both PIEs regardless of the ownership of the peripheral. Thus, a peripheral owned by one CPU can cause an interrupt on the other CPU, if that interrupt is enabled in the other CPU's PIE.
