SYR_DDRB_DP[27:26] = HPDMA write buffer mode status

SYR_DDRB_DP[25:23] = IDC read buffer mode status

SYR_DDRB_DP[22:20] = DSG read buffer mode status

SYR_DDRB_DP[19:17] = AHB bus read buffer mode status

SYR_DDRB_DP[16:14] = HPDMA read buffer mode status

SYR_DDRB_DP[13] = DSG write request to arbiter
