LXM32M 6 Operation

6.1.2Changing the operating state

Bits 8 ... 15 of the word "dmControl" are used to set the operating state.

									dmControl
				15	14		13		12	11	10	9	8
				CU	CH		SH		-	FR	QS	EN	DS
				7	6		5		4	3	2	1	0
				MT	ACTION		ACTION	MODE		MODE	MODE	MODE	MODE
			Figure 8: Structure dmControl bits 8 ... 15
Bit	Name	Meaning				Operating state
8	DS	Disable power stage				6	Operation Enabled -> 4 Ready To Switch On
9	EN	Enable power stage				4	Ready To Switch On -> 6 Operation Enabled
10	QS	Executing a "Quick Stop"				6	Operation Enabled -> 7 Quick Stop Active
11	FR	Execute "Fault Reset"				7	Quick Stop Active -> 6 Operation Enabled
						9	Fault -> 4 Ready To Switch On
12	-	Reserved				Reserved
13	SH	Execute "Halt"				6	Operation Enabled
14	CH	Clear "Halt"				6	Operation Enabled
15	CU	Resume operating mode interrupted by				6 Operation Enabled
		"Halt"

In the case of an access, the bits respond to a 0->1 change to trigger the corresponding function.

If a request for changing the operating state is not successful, this request is ignored. There is no error response.

Ambivalent bit combinations are treated in accordance with the follow- ing priority list (highest priority bit 8, lowest priority bit 14 and bit 15):

•Bit 8 (disable power stage) prior to bit 9 (enable power stage)

•Bit 10 ("Quick Stop") prior to bit 11 ("Fault Reset")

•Bit 13 (execute "Halt") prior to bit 14 (clear "Halt") and bit 15 (resume operating mode interrupted by "Halt")
