16-channel UFm I 2 C-bus 57 mA constant current LED driver
General brightness for the 16 outputs is controlled through 256 linear steps from 00h
(0 % duty cycle = LEDn output off) to FFh (99.6 % duty cycle = maximum brightness).
Applicable to LEDn outputs programmed with LDRx = 11 (LEDOUT0 to LEDOUT3
registers).
When DMBLNK bit is programmed with logic 1, GRPPWM and GRPFREQ registers
define a global blinking pattern, where GRPFREQ contains the blinking period (from
15 Hz to 16.8 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 LEDn outputs programmed with LDRx = 11 (LEDOUT0 to LEDOUT3
registers).
Blinking period is controlled through 256 linear steps from 00h (67 ms, frequency 15 Hz)
to FFh (16.8 s).
