I would like to use description of MSP430 Intrinics described by page 107 of slau132d.pdf.

http://www.ti.com/lit/ug/slau132d/slau132d.pdf
Page 107 : 6.7.1 MSP430 Intrinics

　unsigned long _data16_read_addr(unsigned short addr);
　void _data16_write_addr (unsigned short addr, unsigned long src);

A use wants to calculate CRC of Flash by an in system program.
I am using ccs 5.3.0.
A device is MSP430F247.
There is only the following description in in430.h and I cannot perform the target description.
What should I do for enabling it to use this?
