about AIPS for UART DMA

I am now using 5748G EVB to write a UART DMA demo. I noticed that a similar demo on 5744p there is AIPS_A_init() and AIPS_B_init(). But I don't quite know how to use this module. Is it the same on  5748GEVB?  Here is the code for 5744P.

 

void AIPS_A_Init(void)
{
    // All Master Can go through AIPS_A and all peripheral have no protection

    // Master Privilege Register A

AIPS_A.MPRA.R      = 0x77777777;
    // Peripheral Access Control Register
    AIPS_A.PACR[0].R    = 0x0;
    AIPS_A.PACR[1].R    = 0x0;
    AIPS_A.PACR[2].R    = 0x0;
    AIPS_A.PACR[3].R    = 0x0;
    //AIPS_A.PACR[4].R    = 0x0; - Reserved, not implemented
    AIPS_A.PACR[5].R    = 0x0;
    AIPS_A.PACR[6].R    = 0x0;
    AIPS_A.PACR[7].R    = 0x0;

    // Off-Platform Peripheral Access Control Register
    AIPS_A.OPACR[0].R = 0x0;
    AIPS_A.OPACR[1].R = 0x0;
    AIPS_A.OPACR[2].R = 0x0;
    AIPS_A.OPACR[3].R = 0x0;
    AIPS_A.OPACR[4].R = 0x0;
    AIPS_A.OPACR[5].R = 0x0;
    AIPS_A.OPACR[6].R = 0x0;
    AIPS_A.OPACR[7].R = 0x0;
    AIPS_A.OPACR[8].R = 0x0;
    AIPS_A.OPACR[9].R = 0x0;
    AIPS_A.OPACR[10].R = 0x0;
    AIPS_A.OPACR[11].R = 0x0;
    AIPS_A.OPACR[12].R = 0x0;
    AIPS_A.OPACR[13].R = 0x0;
    AIPS_A.OPACR[14].R = 0x0;
    AIPS_A.OPACR[15].R = 0x0;
    AIPS_A.OPACR[16].R = 0x0;
    AIPS_A.OPACR[17].R = 0x0;
    AIPS_A.OPACR[18].R = 0x0;
    AIPS_A.OPACR[19].R = 0x0;
    AIPS_A.OPACR[20].R = 0x0;
    AIPS_A.OPACR[21].R = 0x0;
    AIPS_A.OPACR[22].R = 0x0;
    AIPS_A.OPACR[23].R = 0x0;
    AIPS_A.OPACR[24].R = 0x0;
    AIPS_A.OPACR[25].R = 0x0;
    AIPS_A.OPACR[26].R = 0x0;
    AIPS_A.OPACR[27].R = 0x0;
    AIPS_A.OPACR[28].R = 0x0;
    AIPS_A.OPACR[29].R = 0x0;
    AIPS_A.OPACR[30].R = 0x0;
    AIPS_A.OPACR[31].R = 0x0;
}
