【0xD0 : Configuration continuous touch】
Name:
CONTTIMES
Address: 0xD0
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)

【0xD1 : Configuration oversampling】
Name:
OSTIMES
Address: 0xD1
Description: OST[3:0]：This register is the number of times of oversampling for canceling chattering to the ‘ON’ or ‘OFF’
operation. If the continuance of the ‘ON’ or ‘OFF’ operations is lower than this register, the
operations are ignored. If this register value is ‘0’, the number of times of oversampling is ‘1’.
Sampling rate：About 14.8msec.

【0xDF : Mask interrupt】
Name:
MASK_INTERRUPT
Address: 0xDF
Description: This register is for mask to the interrupt factor. The masked interrupt factor is not shown on the register
‘Interrupt factor (address 0x10)’, so it does not affect to output port INT.
1 : Masked 0 : Unmasked (default)
MSK_CAL : Mask for Software-calibration finish :
This bit does mask to the interrupt of Software-calibration finish (the bit CAL in the register ‘Interrupt factor’
(address 0x10)).
MSK_ERCAL : Mask for Self-calibration finish :
This bit does mask to the interrupt of Self-calibration finish (the bit ERCAL in the register ‘Interrupt factor’
(address 0x10)).
MSK_PERCAL : Mask for Periodic calibration finish :
This bit does mask to the interrupt of Periodic calibration finish (the bit PERCAL in the register ‘Interrupt
factor’ (address 0x10)).
