Table 6-14.
A value of zero causes the device to enter SLEEP mode where no measurements are
performed.
A value of 255 causes the device to enter Free-run mode where measurements are continuously
performed without entering a low power mode between measurements. This provides the fastest
response time but also the highest power consumption.
Default: 2 (32 ms between key acquisitions)
IO0 – 6: these bits control the direction of the IO pins. A

Default: 0 (all IO's are set as inputs, when using the I
CAL: this bit controls whether the CAL bit causes a CHG transition.
KEY0 – 5 (Key Mask): these bits control whether a change in the corresponding bit in the
detection status register generates a transition on the CHG line. A
cause a CHG request, a 0 stops the corresponding bit from causing a CHG request.
Default: 0xBF (all bits create a CHG request)
