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.
