【0xCF : Configuration continuous touch】
Name:
CONTTIMES
Address: 0xCF
Description: CONTSEL：This register is to select the interrupt frequency by detection continuous touch.
1 : Every continuous touch period.
0 : First detect only.
CONT[5:0]：Continuous touch period is about 0.1[sec] x CONT.
If the setting value is 0x0, continuous touch function is disable.
(0.1sec ≦ Continuous touch period ≦ 6.3sec)
