The data 1 is set to the register “Unexpected Long Press Detection” when unexpected long press is detected. Until unexpected long press is avoided, the unexpected long press is repeatedly detected each configured time. The time until detecting unexpected long press = TIME_UNKNOWN_*[7:0] x Approximately 1s In the case TIME_ UNKNOWN_*[7:0] is set to 0, unexpected long press are not detected. * represent the setting number A and B.

After first long press is detected, subsequent long pressing is referred to as “repeated long press”. These registers configure the time until detecting long press and repeated long press. The data 1 is set to the register “Switch Long Press Detection” when long press is detected. And t he data 1 is set to the register “Switch Repeated Long Press Detection” when repeated long press is detected. The time until detecting long press = TIME_HLD_*[7:0] x Approximately 0.1s In the case TIME_HLD_*[7:0] is set to 0, long press are not detected. The time until detecting repeated long press = TIME_HLD_RPT_*[7:0] x Approximately 0.1s In the case TIME_HLD_RPT_*[7:0] is set to 0, repeated long press is not detected. * represent the setting number from A to G.
