Table 38. Control register 7 description
DCRM is used to select the reset mode of the duration counter. Default value: 0
If DCRM = ‘0’, the counter is reset when the interrupt is no longer active, else if
DCRM = ‘1’ the duration counter is decremented. 1LSB
Latched Interrupt [2:1] Default value: 00
(0: interrupt request not latched; 1: interrupt request latched)
Cleared by reading the IG_SRC1 (31h) and IG_SRC2 (37h) registers.
Interrupt [2:1] 4D option enabled. Default value: 00
When set, IG_CFG1 (30h) and IG_CFG2 (36h) use 4D for position recognition.
