Register description
Note:
RO = Read Only; RW = Read/Write.
Reserved bits must be written with 0s and return 0 upon read; Reserved bytes must not be
accessed otherwise unpredictable results my occur.

CHSEL
Channel select for comparator and PWM logic:
0: Y
1: R
2: G
3: B
2
1
INT_FSEL
INT pin function select:
0: PWM generator output
1: Comparator logic output
3
0
PWM_POL
PWM polarity:
0: Normal (Thin pulse for low values, Wide pulses for high values)
1: Inverted.

0
ADDR_SEL
Address Select: when written with ‘1’, the INT pin goes high impedance;
after a duration T (defined below), the INT pin is sampled and returns to
low impedance.
The device slave address is set accordingly:
INT sampled low: address = 0x20
INT sampled high: address = 0x22.
[6:5]
0
ADDR_SELW
Address select sampling window duration:
0: T = 160 μs (default)
1: T = 80 μs
2: T = 40 μs
3: T = 20 us
This duration allows for INT pin pull-up rise time.

Y_STATUS
Y-channel status register (RO).
Reading this register will cause Y_CNT to be transferred to serial
interface buffer. 5 MSBs are read as zeros.
0
1
RESET
This bit is set after reset. Cleared after first read of STATUS register.
1
0
OVERFLOW
This bit is set upon counter overflow: current counter values are invalid.
2
0
READY
When set, indicates that a new count value is available in the 4 registers
here below.
