Function Description
0x0A
PS Data
Read the PS_Data 8 bits of [7:0].
0x0B
PS Hi_THreshold
The PS Hi_THreshold registers provide the values to be used as the high trigger point for interrupt
generation. An interrupt is generated when the value of proximity conversion is higher than the
threshold.
0x0C
PS Lo_THreshold
The PS Lo_THreshold registers provide the values to be used as the low trigger point for interrupt
generation. An interrupt is generated when the value of proximity conversion is lower than the
threshold.
