16-bit Fm+ I 2 C-bus 100 mA 24 V LED driver
A 97 kHz ?xed frequency signal is used for each output. Duty cycle is controlled through
256 linear steps from 00h (0 % duty cycle = LED output off) to FFh
(99.6 % duty cycle = LED output at maximum brightness). Applicable to LED outputs
programmed with LDRx = 10 or 11 (LEDOUT0 to LEDOUT3 registers).

Description
GRPPWM register
When DMBLNK bit (MODE2 register) is programmed with logic 0, a 190 Hz ?xed
frequency signal is superimposed with the 97 kHz individual brightness control signal.
GRPPWM is then used as a global brightness control allowing the LED outputs to be
dimmed with the same value. The value in GRPFREQ is then a ‘Don’t care’.
General brightness for the 16 outputs is controlled through 256 linear steps from 00h
(0 % duty cycle = LED output off) to FFh (99.6 % duty cycle = maximum brightness).
Applicable to LED outputs programmed with LDRx = 11 (LEDOUT0 to LEDOUT3
registers).
When DMBLNK bit is programmed with logic 1, GRPPWM and GRPFREQ registers
de?ne a global blinking pattern, where GRPFREQ contains the blinking period (from
24 Hz to 10.73 s) and GRPPWM the duty cycle (ON/OFF ratio in %).

Description
GRPFREQ register
GRPFREQ is used to program the global blinking period when DMBLNK bit (MODE2
register) is equal to 1. Value in this register is a ‘Don’t care’ when DMBLNK = 0.
Applicable to LED outputs programmed with LDRx = 11 (LEDOUT0 to LEDOUT3
registers).
Blinking period is controlled through 256 linear steps from 00h (41 ms, frequency 24 Hz)
to FFh (10.73 s).
