Datasheet

Multi-LED Mode Control Registers (0x11–0x12)
In multi-LED mode, each sample is split into up to four time slots, SLOT1 through SLOT4. These control registers determine
which LED is active in each time slot, making for a very flexible configuration.
Each slot generates a 3-byte output into the FIFO. One sample comprises all active slots, for example if SLOT1 and
SLOT2 are non-zero, then one sample is 2 x 3 = 6 bytes. If SLOT1 through SLOT3 are all non-zero, then one sample
is 3 x 3 = 9 bytes.
The slots should be enabled in order (i.e., SLOT1 should not be disabled if SLOT2 or SLOT3 are enabled).
*Both LED3 and LED4 are wired to Green LED. Green LED sinks current out of LED3_PA[7:0] and LED4_PA[7:0] con-
figurationin Multi-LED Mode and SLOTx[2:0] = 011.
