PS2 Interrupt Mode applies only when PS2_IE is also set.
00: PS2_INT is set whenever a PS2 measurement has completed.
01: PS2_INT is set whenever the current PS2 measurement crosses the PS2_TH
threshold.
11: PS2_INT is set whenever the current PS2 measurement is greater than the
PS2_TH threshold.
PS1 Interrupt Mode applies only when PS1_IE is also set.
00: PS1_INT is set whenever a PS1 measurement has completed.
01: PS1_INT is set whenever the current PS1 measurement crosses the PS1_TH
threshold.
11: PS1_INT is set whenever the current PS1 measurement is greater than the
PS1_TH threshold.
ALS Interrupt Mode function is defined in conjunction with ALS_IE[1:0].
ALS_IE[1:0] / ALS_IM[2:0]:
00 / 000: Neither ALS_INT[1] nor ALS_INT[0] is ever set.
01 / 000: ALS_INT[0] sets after every ALS_VIS sample.
x1 / x01: Monitors ALS_VIS channel, ALS_INT[0] asserts if measurement exits window
between ALS_LOW_TH and ALS_HIGH_TH.
x1 / x11: Monitors ALS_IR channel, ALS_INT[0] asserts if measurement exits window
between ALS_LOW_TH and ALS_HIGH_TH.
1x /10x: Monitors ALS_VIS channel, ALS_INT[1] asserts if measurement enters win-
dow between ALS_LOW_TH and ALS_HIGH_TH.
1x /11x: Monitors ALS_IR channel, ALS_INT[1] asserts if measurement enters window
between ALS_LOW_TH and ALS_HIGH_TH.
