Ambient and Infrared Proximity Sensor
The 2 bytes here (ALSDATA[13:0]) hold the results of the ALS signal conversion. The resolution and bit length of the
result is controlled by the value of ALSTIM[1:0] and ALSPGA[1:0] bits. The result is always right justified in the two
registers, and the unused high bits are zero.
OFL indicates an overflow condition on the ALS channel. If this occurs, set the ALS range (ALSPGA[1:0]) to a higher
range. If the OFL bit is set to 1 (there is an overflow condition), and the ALSINTE bit is set to 1 (enabled), then the
ALSINTS bit is set to 1 and the INT pin is pulled low.
The data in this register could be the green channel, infrared channel, or ALS readings (green channel, infrared chan-
nel readings), depending on the mode selected by the user.
Internal update of these two registers is disabled during I
the ADC and the I
Therefore, when reading the 2 bytes of this register, the master should not send a STOP command between the 2-byte
reads. Instead, a Repeated START (Sr) command should be used. The exact read sequence using the Repeated
START command is shown in the I
The byte here (PRXDATA[7:0]) hold the results of the proximity receive signal conversion. Internal update of the register
is disabled during I
