GRPFREQ register
(1) R = read, W = write
(2) Default value
GRPFREQ is used to program the global blinking period when DMBLNK bit (MODE2 register) is equal to 1.
NOTE
The value in GRPFREQ must be programmed to 00h when DMBLNK = 0.
Applicable to LED output 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).

(1) R = read, W = write
(2) 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 is individual brightness can be controlled through its PWMx register.
LDRx = 11 : LED driver x is individual brightness and group dimming/blinking can be controlled through its PWMx
register and the GRPPWM registers.
