PEa[x]
This register provides a way for software to emulate the assertion of a particular Peripheral
interrupt. The actual interrupt is the OR or the normal interrupt source and each of these test
register bits. The order is exactly the same as the PSa in ICTL Peripheral Interrupt Status All
Register. The PEa[x] bits ARE masked by the Per_Mask setting, so they operate as much as
possible as the real interrupt source. Test assertion of a Periperhal source will cause HI-int
or LO-int indications which will be reflected in the Main or Critical status registers. If relying
on PEa[x] assertion/negation to emulate and test an ISR routine it is important to disable all
source modules so that real source interrupts will not disturb the test generated interrupt.
