8 / 13 page IS31FL3193 Integrated Silicon Solution, Inc. – www.issi.com 8 Rev. C, 11/27/2014 Table 4 01h Breathing Control Register Bit D7:D6 D5 D4 D3 D2 D1:D0 Name - RM HT - BME CSS Default 00 0 0 0 0 00 The Breathing Control Register sets the breathing function. RM Ramping Mode Enable 0 Disable 1 Enable HT Hold Time Selection 0 Hold on T2 1 Hold on T4 BME Breathing Mark Enable 0 Disable 1 Enable CSS Channel Selection 00 OUT1 01 OUT2 10 OUT3 Others Unavailable Table 5 02h LED Mode Register Bit D7:D6 D5 D4:D0 Name - RGB - Default 00 0 00000 The LED Mode Register sets operation mode of IS31FL3193. RGB RGB Mode Selection 0 PWM Control Mode 1 One Shot Programming Mode Table 6 03h Current Setting Register Bit D7:D5 D4:D2 D1:D0 Name - CS - Default 000 000 00 The Current Setting Register stores the maximum current setting, IMAX, for all of the LED output channels. CS Current Setting 000 42mA 001 10mA 010 5mA 011 30mA 1xx 17.5mA Table 7 04h~06h PWM Register(OUT1~OUT3) Bit D7:D0 Name PWM Default 0000 0000 The value in the PWM Registers modulate the RGB LEDs in 256 steps. The value of the PWM Registers decide the average output current of OUT1~OUT3. The average output current may be computed using the Formula (1): 7 0 2 * ] [ 256 n n MAX OUT n D I I (1) Where D[n] stands for the individual bit value, 1 or 0, in location n. For example: if D7:D0 = 10110101, IOUT = IMAX (2 0+22+24+25+27)/256 IMAX is set by Current Setting Register. 07h PWM Update Register The data sent to the PWM Registers and the LED Control Registers will be stored in temporary registers. A write operation of “0000 0000” to the Update Register is required to update the registers (04h~06h, 1Dh). Table 8 0Ah~0Ch T0 Register (OUT1~OUT3) Bit D7:D4 D3:D0 Name T0 - Default 0000 0000 The T0 Registers set the T0 time in One Shot Programming mode. T0 T0 Setting 0000 0s 0001 0.13s 0010 0.26s 0011 0.52s 0100 1.04s 0101 2.08s 0110 4.16s 0111 8.32s 1000 16.64s 1001 33.28s 1010 66.56s Others Unavailable |
