OUTPUT SIDE, “R
EGISTER
” 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 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. Each value
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.
