Name | Bit | Access | Description | ||||
---|---|---|---|---|---|---|---|
EN_DISPLAY_LED_FAULT | 7 | R/W | 0 = LED open/short faults disabled
1 = LED open/short faults enabled |
||||
DRV_LED_CURRENT_SCALE[2:0] | 6:4 | R/W | Scales the maximum LED current when EN_EXT_LED_CUR_CTRL = 0 Effective for both modes – display and cluster.
000 = 25 mA 001 = 30 mA 010 = 50 mA 011 = 60 mA 100 = 80 mA 101 = 100 mA 110 = 120 mA 111 = 150 mA |
||||
LED_STRING_CONF[2:0] | 3:1 | R/W | LED current sink configuration
000 = 4 separate LED strings with 90° phase shift 001 = 3 separate LED strings with 120° phase shift (String 4 in cluster mode or not used) 010 = 2 separate LED strings with 180° phase shift (Strings 3 and 4 in cluster mode or not used) 011 = 1 LED string. (Strings 2,3 and 4 in cluster mode or not used) 100 = 2 LED strings (1+2, 3+4) with 180° phase shift. Tied strings with same phase. 101 = 1 LED string (1+2+3+4). Tied strings with same phase 110 = 1 LED string (1+2). 1st and 2nd strings tied with same phase, strings 3 and 4 are in cluster mode or not used 111 = All strings are used in cluster mode |
||||
EN_PWM_I | 0 | R/W | Enable Hybrid PWM and Current dimming mode
0 = Disabled, dimming only with PWM 1 = Enabled |
