Wcd9341 Datasheet -

The WCD9341 has a that routes 1-bit data directly to the analog low-pass filter, bypassing the PCM decimation and interpolation filters. Datasheet stipulates:

8.5/10 – excellent for its era, but showing its age in power efficiency and register complexity. wcd9341 datasheet

1. Assert RESET low, wait t_RST_LOW (datasheet) 2. Deassert RESET, wait t_RST_HIGH 3. Enable VDD and VGL/VGH regulators in specified order 4. Delay per t_PWR_STABLE 5. Send register block: interface config, display timing, gamma LUT 6. Enable backlight with ramped PWM duty cycle 7. Set display on command The WCD9341 has a that routes 1-bit data
