Bits	Name	Description
[31:10]	-	Read undefined. Write as zero.
[9]	MPMCDLLCALIBREQ	Value of DLL calibration request signal MPMCDLLCALIBREQ. Read: Read the value of this field if the MPMCITCR T bit is HIGH. Read the value of the MPMCDLLCALIBREQ output signal if the MPMCITCR T bit is LOW. Write: 0 = Clear this field if the MPMCITCR T bit is HIGH. 1 = Set this field if the MPMCITCR T bit is HIGH.
[8:3]	-	Read undefined. Write as zero.
[2]	MPMCEBIREQ	Read: Read the value of this field if the MPMCITCR T bit is HIGH. Read the value of the MPMCEBIREQ output signal if the MPMCITCR T bit is LOW. Write: 0 = Clear this field and the MPMCEBIREQ output signal if the MPMCITR T bit is HIGH 1 = Set this field and the MPMCEBIREQ output signal if the MPMCITR T bit is HIGH.
[1]	MPMCRPVHHOUT	Read: Read the value of this field if the MPMCITCR T bit is HIGH. Read the value of the MPMCRPVHHOUT output signal if the MPMCITCR T bit is LOW. Write: 0 = Clear this field and the MPMCRPVHHOUT output signal if the MPMCITR T bit is HIGH. 1 = Set this field and the MPMCRPVHHOUT output signal if the MPMCITR T bit is HIGH.
[0]	MPMCSREFACK (SA)	Self-refresh acknowledge. Read: Read the value of this field if the MPMCITCR T bit is HIGH. Read the value of the MPMCSREFACK output signal if the MPMCITCR T bit is LOW. Write: 0 = Clear this field and the MPMCSREFACK output signal if the MPMCITR T bit is HIGH. 1 = Set this field and the MPMCSREFACK output signal if the MPMCITR T bit is HIGH.
