MSP430FR5994: Large Variable Write to FRAM through DMA; Destination Address Definition

Hi all,

I am trying to write a very large (128kB at the moment) array to FRAM from the ADC. So far, I think I have set up the ADC to sample correctly, and have DMA transfers timed such that the sampling rate is 100 kHz. 

My issue lies in the following code:

    __data16_write_addr((unsigned short) &DMA0SA,(unsigned long) &ADC12MEM0);
                                                // Source fixed address (ADC12 memory)
    __data16_write_addr((unsigned short) &DMA0DA,(unsigned long) 0x24BFF);
                                                // Destination incremented address (FRAM, see datasheet)

The intrinsic functions I've found for write addresses are 16-bit, correct? And because they are 16-bit, I cannot access the register 0x24BFF in the FRAM? How can I make the destination address be recognized as 20-bit? I see other intrinsic functions, but none of them appear to be for addresses. 

Currently, I get an error:

Description Resource Path Location Type
#770-D conversion from pointer to smaller integer MSP430FR5994_DAQ_main.c /16_GE_DAQ_v01 line 332 C/C++ Problem

This error applies to both lines of the above code.

I'm fairly new to this stuff, so any help is appreciated!

Thanks.
