10 / 22 page IS31FL3731 Integrated Silicon Solution, Inc. – www.issi.com 10 Rev.D, 04/22/2013 REGISTER CONTROL FRAME REGISTER Table 4 00h ~ 11h LED Control Register Bit D7:D0 Name CX-8 : CX-1 or CX-16 : CX-9 Default xxxx xxxx The LED Control Registers store the on or off state of each LED in the Matrix A and B. Please refer to the detail information in Table 7. CX-Y LED State Bit 0 LED off 1 LED on Figure 8 in Page 11 shows the ordering of CX-Y. Table 5 12h ~ 23h Blink Control Register Bit D7:D0 Name CX-8 : CX-1 or CX-16 : CX-9 Default xxxx xxxx The Blink Control Registers configure the blink function of each LED in the Matrix A and B. Please refer to the detail information in Table 7. CX-Y Blink Control Bit 0 Disable 1 Enable Figure 8 in Page 11 shows the ordering of CX-Y. Table 6 24h ~ B3h PWM Register Bit D7:D0 Name PWM Default xxxx xxxx PWM Registers modulate the 144 LEDs in 256 steps. The value of the PWM Registers decides the output current of each LED. The output current may be computed using the Formula (1): 7 0 PWM 2 ] [ 256 I n n LED n D I (1) Where D[n] stands for the individual bit value, 1 or 0, in location n. For example: if D7:D0 = 10110101, IPWM = ILED (2 0+22+24+25+27)/256 ILED is set by the external resistor, REXT, ILED = 64.7/REXT. For example, when REXT = 20kΩ, ILED = 64.7/20 = 3.2mA. |
