PS1_TH is an 8-bit compressed value representing a 16-bit threshold value. The uncom-
pressed value represented by PS1_TH is compared to PS1 measurements during auton-
omous operation for interrupting the host.
PS2_TH is an 8-bit compressed value representing a 16-bit threshold value. The
uncompressed value represented by PS2_TH is compared to PS2 measurements dur-
ing autonomous operation for interrupting the host.
Reserved.
LED3_I Represents the irLED current sunk by the LED3 pin during a PS measure-
ment. See PS_LED21 Register for additional details.
On the Si1141 and Si1142, these bits must be set to zero.
