KEY0 – 5 (AKS Mask): these bits control which keys are included in the AKS group. A
the corresponding key is included in the AKS group and may only go into detect when it has the
largest signal change of any key in the group. A 0 means that it is excluded and can go into
detect whenever its threshold is passed.
Default: 0x00 (no keys are within the AKS group)
IO0 – 6 (PWM Mask): these bits control which IOs that are configured as outputs, and its user
output buffer activated, will output a PWM signal. A
signal, a 0 means the output generates a logic level. The active level of the output (both logical
and PWM) is determined by the Active level mask. See
precedence and example usage.
Default: 0x00 (PWM is off on all IOs)
IO0 – 6 (Detection Mask): these bits control which IOs that are configured as outputs will be
controlled by their corresponding capacitive key. A
output when key “n” is detecting a touch. A 0 means that the output is controlled by the output
buffer. See
Default: 0x3F (all IOs are controlled by key status)
IO0 – 6 (Active Level Mask): these bits control the active logic level for the IOs that are
configured as outputs. A
output is active low. See
Default: 0 (all IOs are active low output)
