PCD default interrupt handler

[srlevitt2]

On a dspic30F6012 using CCS PCD compiler.
If I define a default interrupt handler, inside that function can I use "interrupt_active(INT_RDA2)" to check if I have been called as a character is received on uart2?

Something like:

Basically, yes.
There are obviously 'caveats'. For exqample, if a a result of this, you call a getc, inside the interrupt handler, but you also want to use getc outside (since you are not really using an interrupt driven receive), you will get interrupts being disabled around the external getc. Remember also, that 'int_default', will only get called, if an interrupt has occured, and is enabled, and there is no handler present for this interrupt.....

Strictly spoken, interrupt_active(INT_RDA2) doesn't tell, that the U2RX interrupt is being serviced. It means, that
INT_RDA2 is pending, but a different interrupt may be serviced first.
