10 / 15 page  IS31FL3196 Integrated Silicon Solution, Inc. — www.issi.com Rev.A, 03/27/2012 10 Table 9 07h~0Ch PWM Register(OUT1~OUT6) Bit D7:D0 Name PWM Default 0000 0000 The PWM Registers can modulate RGB light with 256 different items. The value of PWM Registers decide the average output current of OUT1~OUT6. The average output current may be computed using the Formula (1): 7 0 OUT 2 ] [ 256 I n n MAX n D I (1) Where “n” indicates the bit location in the respective PWM register. For example: D7:D0 = 10110101, IOUT = IMAX (2 0+22+24+25+27)/256 IMAX is set by Configuration Register2 (04h). 10h Data Update Register The data sent to the PWM Registers and the LED Control Registers will be stored in temporary registers. A write operation of any 8-bit value to the Data Update Register is required to update the registers (01h, 07h~0Ch). Table 10 11h~16h T0 Register (OUT1~OUT6) Bit D7:D6 D5:D4 D3:D0 Name - B A Default 00 00 0000 The T0 Registers set the T0 time in One Shot Programming Mode. T0 = τ×A×2 B A = 0~15, B = 0~3 and τ = 260ms (Typ.) For example, the max T0 is 260ms×15×2 3 = 31.2s Table 11 1Ah~1Bh T1~T3 Register (RGB1~RGB2) Bit D7 D6:D4 D3 D2:D0 Name DT B - A Default 0 000 0 000 The T1~T3 Registers set the T1~T3 time in One Shot Programming Mode. DT Double Time 0 T3 =T1 1 T3 = 2T1 If A = 0~4, T1 = T3 = τ×2 A, τ = 260ms (Typ.) If A = 5~6, the breathing function disable. If A = 7, T1= T3 = 0.1ms. If B = 1~7, T2 = τ×2 B-1, τ = 260ms (Typ.) If B = 0, T2 = 0s. For example, the max T1&T3 is 260ms×2 4 = 4.16s. The max T2 is 260ms×2 6 = 16.64s. Table 12 1Dh~22h T4 Register (OUT1~OUT6) Bit D7:D6 D5:D4 D3:D0 Name - B A Default 00 00 0000 The T4 Registers set the T4 time in One Shot Programming Mode. T4 = τ×A×2 B A = 0~15, B = 0~3 and τ = 260ms (Typ.) For example, the max T4 is 260ms×15×2 3 = 31.2s 26h Time Update Register The data sent to the time registers (11h~16h, 1Ah~1Bh, 1Dh~22h) will be stored in temporary registers. A write operation of any 8-bit data to the Time Update Register is required to update the registers (11h~16h, 1Ah~1Bh, 1Dh~22h). FFh Reset Register Once user writes any 8-bit data to the Reset Register, IS31FL3196 will reset all registers to default value. On initial power-up, the IS31FL3196 registers are reset to their default values for a blank display. |
