Product data sheet
7.3.6 LEDOUT0 to LEDOUT3, LED driver output state
7.3.7 SUBADR1 to SUBADR3, I
Table 10.
Legend: * default value.
LDRx = 00 — LED driver x is off (default power-up state).
LDRx = 01 — LED driver x is fully on (individual brightness and group dimming/blinking
not controlled).
LDRx = 10 — LED driver x individual brightness can be controlled through its PWMx
register.
LDRx = 11 — LED driver x individual brightness and group dimming/blinking can be
controlled through its PWMx register and the GRPPWM registers.
Table 11.
Legend: * default value.
Subaddresses are programmable through the I
E4h, E8h, and the device(s) will not acknowledge these addresses right after power-up
(the corresponding SUBx bit in MODE1 register is equal to 0).
