ADE3800
● XCLK: Crystal oscillator, usually 27 MHz.
● INCLK: ADC Sampling clock frequency, depends on input video mode pixel rate.
● DOTCLK and OUTCLK: Related to Panel Output Pixel Rate.
● SCLK: Scale Clock used for the line buffer Ram and picture zooming.
● If some bit fields are missing, these bits are marked as "reserved":
— return 0 when read, but it is also the user's duty to mask them upon readout, to ensure
compatibility with later device releases
— must be written to 0 when the whole register is written
in all cases, the default reset value always prevails
● An asterisk denotes the default reset value for the corresponding bit(s).
● Unless all addresses and registers values are in hexadecimal.
● “not sticky” means dynamically updated (set or reset) by hardware, not a static bit.
● A “sticky” bit, once set remains set until the user clears it.
● When a value is followed by “typ” this means it is a typical value and PVT dependent.
● If a time or delay value does not have “min/typ/max” information, it is proportional to the XCLK
frequency.
● Any register names containing HW are shadow registers: they report which value is currently
being used by the chip.
● When a register bit field list has one bold option, it is the only choice for normal mode of
operation.
● TCON must always be programmed for any panel type.
● Values spread out over several registers are organised as follows:
32-bit values
24-bit values
16-bit values
