Table 6-14. Module Status n Register (MDSTATn) Field Descriptions

Bit	Field	Value	Description
31-18	Reserved	0	Reserved
17	EMUIHB		Emulation Alters Module State. This bit applies to DSP module only (module 39). This field is 0 for
			all other modules.
		0	No emulation altering user-desired module state programmed in the NEXT bit in MDCTL39.
		1	Emulation altered user-desired state programmed in the NEXT bit in MDCTL39.
			If you desire to generate a PSCINT upon this event, you must set the EMUIHBIE bit in MDCTL39..
16	EMURST		Emulation Alters Module Reset. This bit applies to DSP module only (module 39). This field is 0 for
			all other modules.
		0	No emulation altering user-desired module reset state.
		1	Emulation altered user-desired module reset state.
			If you desire to generate a PSCINT upon this event, you must set the EMURSTIE bit in MDCTL39.
15-13	Reserved	0	Reserved
12	MCKOUT		Module clock output status. Shows actual status of module clock.
		0	Module clock is off.
		1	Module clock is on.
11	Reserved	1	Reserved
10	MRST		Module reset status. Reflects actual state of module reset.
		0	Module reset is asserted.
		1	Module reset is de-asserted.
9	LRSTDONE		Local reset done. Software is responsible for checking if local reset is done before accessing this
			module. This bit applies to the DSP module only (module 39). This field is 1 for all other modules.
		0	Local reset is not done.
		1	Local reset is done.
8	LRST		Module local reset status. This bit applies to the DSP module only (module 39).
		0	Local reset is asserted.
		1	Local reset is de-asserted.
7-6	Reserved	0	Reserved
5-0	STATE	0-3Fh	Module state status. Indicates current module status.
		0	SwRstDisable state
		1h	SyncReset state
		2h	Disable state
		3h	Enable state
		4h-3Fh	Indicates transition
