13.7 Main String Duty Cycle register, High Byte (MDUTYHIGH, 0x34)
Contains the upper 8-bits of the 12-bit MSL2023 main string duty cycle setting. The remaining 4-bits are in register 0x35.
The registers combine to form the main string duty cycle, a linear relation where 0x000 = 0% to 0xFFF = 100%. When
changed, the duty cycle updates at the beginning of the next output PWM period.
Table 13-7. Main String Duty Cycle High register (MDUTYHIGH, 0x34), defaults highlighted.
13.8 Main String Duty Cycle register, Low Byte (MDUTYLOW, 0x35)
Contains the lower 4-bits of the 12-bit MSL2023 main string duty cycle setting. The upper 8-bits are in register 0x34. The
registers combine to form the main string duty cycle, a linear relation where 0x000 = 0% to 0xFFF = 100%. When
changed, the duty cycle updates at the beginning of the next output PWM period.
Table 13-8. Main String Duty Cycle Low register (MDUTYLOW, 0x35), defaults highlighted.
13.9 Color Adjust String Duty Cycle register, High Byte (CADUTYHIGH, 0x36)
Contains the upper 8-bits of the 12-bit MSL2023 color-adjust string duty cycle setting. The remaining 4-bits are in register
0x37. The registers combine to form the color-adjust string duty cycle, a linear relation where 0x000 = 0% to 0xFFF =
100%. When changed, the duty cycle updates at the beginning of the next output PWM period.
Table 13-9. Color Adjust String Duty Cycle High register (CADUTYHIGH, 0x36), defaults highlighted.
13.10 Color Adjust String Duty Cycle register, Low Byte (CADUTYLOW, 0x37)
Contains the lower 4-bits of the 12-bit MSL2023 color-adjust string duty cycle setting. The upper 8-bits are in register
0x36. The registers combine to form the color-adjust string duty cycle, a linear relation where 0x000 = 0% to 0xFFF =
100%. When changed, the duty cycle updates at the beginning of the next output PWM period.
