31.7.12 Matrix Group Configuration Register 2
Name:
MGCFG2
Access Type: Read/Write
Offset: 0x38
Reset Value: 0x00000000
• ACCTRL: Analog Comparator Control
When written to one, allows the CAT to disable the analog comparators when they are not needed. When written to zero, the
analog comparators are always enabled.
• CONSEN: Consensus Filter Length
For QMatrix sensors, specifies that discharge will be terminated when CONSEN out of the most recent 5 comparator samples
are positive. For example, a value of 3 in the CONSEN field will terminate discharge when 3 out of the most recent 5 comparator
samples are positive. When CONSEN has the default value of 0, discharge will be terminated immediately when the comparator
output goes positive.
• CXDILEN: Cx Capacitor Discharge Length
For QMatrix sensors, specifies how many burst prescaler clock cycles the CAT should use to discharge the Cx capacitor at the
end of each burst cycle.
• SYNCTIM: Sync Time Interval
When non-zero, determines the number of prescaled clock cycles between the start of the acquisition on each X line for QMatrix
acquisition.
