Output side, "Register" 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. The CDATA, GDATA and BDATA
and PDATA values are the ADC values for Clear and RGB photodiodes. Each is read via one 8-bit
register.
•
ID (0x92) – The ID register provides the value for the part number.
•
Status (0x93) – Internal status. Interrupts active (2 bits) and ALS valid bits are here. The
contents of the register is decoded as follows:
1.
"ALS OK" or "ALS Not OK" will be displayed based on the AVALID bit (bit 0).
•
CDATA (0x94, 0x95): This value is controlled by the Clear/IR button on the Functional Input
tab.
1.
CDATAL (0x94) – The lower 8 ADC bits of the Clear or IR photodiode.
2.
CDATAH (0x95) – The upper 8 ADC bits of the Clear or IR photodiode.
•
RDATA (0x16, 0x17):
1.
RDATAL (0x16) – The lower 8 ADC bits of the Red photodiode.
2.
RDATAH (0x17) – The upper 8 ADC bits of the Red photodiode.
•
GDATA (0x18, 0x19):
1.
GDATAL (0x18) – The lower 8 ADC bits of the Green photodiode.
2.
GDATAH (0x19) – The upper 8 ADC bits of the Green photodiode.
•
BDATA (0x1A, 0x1B):
1.
BDATAL (0x1A) – The lower 8 ADC bits of the Blue photodiode.
2.
BDATAH (0x1B) – The upper 8 ADC bits of the Blue photodiode.
•
Interrupts
These buttons clear or set an interrupt.
1.
IForce – forces an Interrupt
2.
CIClear – clears an Interrupt on the Clear Channel
3.
AIClear – clears all Interrupts
