51 / 63 page ![]() Data Sheet ADP5350 Rev. B | Page 51 of 63 Table 63. ILED5_SET, Register Address 0x2C Bit Descriptions Bit No. Mnemonic Access Default Description 7 BL_LED5 R/W 0 This bit sets LED5 as the grouped backlight or individual current sink. 0 = set as individual current sink. 1 = set as grouped backlight. 6 Not used R Not used. [5:0] ILED5[5:0] R/W 000000 Those bits set the individual LED current setting for LED5. This setting is not effective if LED5 is configured as the grouped LED backlight. A square law algorithm for 64 levels is used. 000000 = 0 mA. 000001 = 0.005 mA. 000010 = 0.020 mA. … 111101 = 18.750 mA. 111110 = 19.370 mA. 111111 = 20 mA. Table 64. BL_FR, Register Address 0x2D Bit Descriptions Bit No. Mnemonic Access Default Description [7:4] BL_FO[3:0] R/W 0000 These bits set the fade out timer for the grouped LED backlight. The timer setting applies to the specific time starting from the maximum LED current code fade out to zero. Therefore, the real fade out time is shorter if the maximum LED current code is not being used. 0000 = fade-out disabled. 0001 = 0.3 sec. 0010 = 0.6 sec. … 1101 = 3.9 sec. 1110 = 4.2 sec. 1111 = 4.5 sec. [3:0] BL_FI[3:0] R/W 0000 These bits set the fade in timer for the grouped LED backlight. The timer setting applies to the specific time starting from zero fading into the maximum LED current code. Therefore, the real fade in time is shorter if the maximum LED current code is not being used. 0000 = fade in disabled. 0001 = 0.3 sec. 0010 = 0.6 sec. … 1101 = 3.9 sec. 1110 = 4.2 sec. 1111 = 4.5 sec. Table 65. LED3_BLINK, Register Address 0x2E Bit Descriptions Bit No. Mnemonic Access Default Description [7:4] LED3_OFF[3:0] R/W 0000 These bits set the off timer for the LED3 blinking feature (not effective if this LED channel is configured as the grouped LED backlight). 0000 = the blinking feature is disabled. 0001 = 0.250 sec. 0010 = 0.500 sec. 0011 = 0.750 sec. … 1110 = 3.500 sec. 1111 = 3.750 sec. |
