Create Large Arrays for PIC24 or dsPIC33

With C30, in the compiler option, check "Enable large arrays".

With XC16, check "Allow arrays larger than 32K" in the Memory model.

		if the JTAGEN is programmed, the MCHP TAP controller must be selected immediately after any PROGRAM command.  This can be done by using a SendCommand(MTAP_SW_MTAP) pseudo operation.  After 400 us, the EJTAG TAP controller can be selected again by calling the SendCommand(MTAP_SW_ETAP) pseudo operation.  -- ch 16.3
