TAB
The value of internal registers is
displayed on this tab. Register
values cannot be set here. To set
registers use the Register tab on
the input side of the screen.
Controls are provided for clearing
the Proximity interrupt (PINT) and
the ALS interrupt (AINT). The
current interrupt status is also
shown.
The CDATA, RDATA, GDATA, and
BDATA are the ADC values from
the Clear, Red, Green and Blue
channel photodiodes. PDATA
values are the proximity detection
value. Each is read via two 8-bit
registers.
•
Status (0x13) – Internal status. Interrupts active (2 bits) and ALS valid bits are here.
•
ID (0x12) – The ID register provides the value for the part number.
•
CDATA (0x14, 0x15):
1.
CDATA (0x14) – The lower 8 ADC bits of the Clear photodiode.
2.
CDATAH (0x15) – The upper 8 ADC bits of the Clear photodiode.
•
RDATA (0x16, 0x17):
1.
IRDATA (0x16) – The lower 8 ADC bits of the Red photodiode.
2.
IRDATAH (0x17) – The upper 8 ADC bits of the Red photodiode.
•
GDATA (0x18, 0x19):
1.
IRDATA (0x18) – The lower 8 ADC bits of the Green photodiode.
2.
IRDATAH (0x19) – The upper 8 ADC bits of the Green photodiode.
•
BDATA (0x1A, 0x1B):
1.
IRDATA (0x1A) – The lower 8 ADC bits of the Blue photodiode.
2.
IRDATAH (0x1B) – The upper 8 ADC bits of the Blue photodiode.
•
PDATA (0x1C, 0x1D):
1.
PDATA (0x1C) – The lower 8 bits of the proximity value.
2.
PDATAH (0x1D) – The upper 8 bits of the proximity value.
