DLYCNT01M (LED1 PWM Delay setting register–High 4bit-: Read/Write)
●ADDR=33h～50h
This register is used to make setting of pulse duty for PWM light modulation in a total of 12 bits, i.e., Bit7-0 when
ADDR 11h and Bit3-0 when ADDR 12h.
This register is used to make setting of PWM pulse width for LED2 to LED16. The setting procedure is the same as that for
LED1 with ADDR set to 0Ah and 0Bh.
This register is used to make setting of delay width for PWM light modulation in a total of 12 bits, i.e., Bit7-0 when
ADDR 32h and Bit3-0 when ADDR 2Eh.
This register is used to make PWM delay width setting for LED2 to LED16. The setting procedure is the same as that for
LED1 with ADDR set to 2Ah and 2Bh.
