GRPFREQ is used to program the global blinking period when the DMBLNK bit (MODE2 register) is equal to 1.
Value in this register is a Don't care when DMBLNK = 0. This is applicable to LED output programmed with
LDRx = 11 (LEDOUT0 and LEDOUT1 registers).
The blinking period is controlled through 256 linear steps from 00h (41 ms, frequency 24 Hz) to FFh (10.73 s).
Global blinking period (seconds) = (GFRQ[7:0] + 1) / 24

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.
