Table 36-7. DMM Global Control Register (DMMGLBCTRL) Field Descriptions
Bit Field Value Description
31-25 Reserved 0 Reads returns 0. Writes have no effect.
24 BUSY Busy indicator.
0 The DMM does not currently receive data and has no data in its internal buffers, which
needs to be transferred.
1 The module is currently receiving data, or has data in its internal buffers.
23-19 Reserved 0 Reads returns 0. Writes have no effect.
18 CONTCLK Continuous DMMCLK input.
User and privilege mode read, privilege mode write:
0 DMMCLK is expected to be suspended between two packets.
1 DMMCLK is expected to be free running between packets.
17 COS Continue on suspend. Influences behavior of module while in debug mode. In all cases the
corresponding interrupt will be set.
User and privilege mode (read):
0 Packets will not be received during debug mode. Before entering debug mode, the ongoing
reception of a packet will be finished and the value will be written to the destination.
1 Continue receiving packets and update destination, while in debug mode.
Privilege mode (write):
0 Disable data reception while in debug mode.
1 Enable data reception while in debug mode.
16 RESET Reset. This bit resets the state machine and the registers to its reset value, except the
RESET bit itself. It must be cleared by writing to it.
User and privilege mode (read):
0 No reset of DMM module.
1 Reset of DMM module.
Privilege mode (write):
0 No reset of DMM module.
1 Reset DMM module to its reset state.
15-11 Reserved 0 Reads returns 0. Writes have no effect.
