bit 1: Disable Charge Pump
bit 0: Disable Clock
Disable Charge Pump and Clock require about 267ms
Enable Charge Pump and Clock require about 10ms
Disable Charge Pump and Clock require about 10ms
Enable Charge Pump and Clock require about 100 to 300ms
Notes:
- Introduced a refresh display message, which copies RAM to display
- Charge pump and clock are only enabled for the transfer RAM to display
- Charge pump is always enabled. Charge pump can be enabled/disabled via power save message
- U8x8 will not really work because of the two buffers in the SSD1606, however U8g2 should be ok.

LUT for the 296x128 device (IL3820)
LUT (cmd: 0x032 has 30 bytes)
section 6.8 of the datasheet mentions 256 bits = 32 bytes for the LUT
chapter 7 tells 30 bytes
according to section 6.8:
20 bytes waveform
10 bytes timing
1 byte named as VSH/VSL
1 empty byte
according to the command table, the lut has 240 bits (=30 bytes * 8 bits)
LUT / Refresh time
total_refresh_time = (refresh_lines + dummy_lines*2)*TGate*TS_Sum/f_OSC
f_OSC=1MHz (according to the datasheets)
refreh_lines = 296 (for the waveshare display, 0x045 cmd)
dummy_lines = 22 (for the upcoming u8g2 code, 0x03a cmd)
TGate = 62 (POR default, 0x03b cmd)
TS_Sum: Sum of all TS entries of the second part of the LUT
f_OSC: 1MHz according to the datasheet.
so we have
total_refresh_time = 21080*TS_Sum/1000000 = 21ms * TS_Sum
This file includes two devices:
u8x8_d_il3820_296x128 --> includes LUT which is probably from the WaveShare 2.9 Vendor
u8x8_d_il3820_v2_296x128 --> includes LUT which was optimized for faster speed and lesser flicker
