Product data sheet
7.3.5 Group frequency, GRPFREQ
7.3.6 LED driver output state, LEDOUT
7.3.7 I
Table 10.
Legend: * default value.
GRPFREQ is used to program the global blinking period when DMBLNK bit (MODE2
register) is equal to logic 1. Value in this register is a ‘don’t care’ when DMBLNK = 0.
Applicable to LED outputs programmed with LDRx = 11 (LEDOUT register).
Blinking period is controlled through 256 linear steps from 00h (41 ms, frequency 24 Hz)
to FFh (10.73 seconds).
Table 11.
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 12.
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 logic 0).
