The irq/altirq number can be one of the interrupt request numbers 45 to 53. If the
irq
irq
parameter of the interrupt attribute is used, the compiler creates the external
symbol name __Interruptn, where n is the vector number. Therefore, the C
identifiers _Interrupt45 through _Interrupt53 are reserved by the compiler. In
the same way, if the altirq parameter of the interrupt attribute is used, the compiler
creates the external symbol name __AltInterruptn, where n is the vector number.
Therefore, the C identifiers _AltInterrupt45 through _AltInterrupt53 are
reserved by the compiler.

Non-SMPS dsPIC30F DSCs Interrupt Vectors
Most dsPIC30F DSCs are not Switch Mode Power Supply (SMPS) devices. Consult
your device data sheet to see if it is an SMPS device.
