Important Information

Important Information

● 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

_M or _1
