To use this method, set CR0(0) = 1 using state machine accessing (multiple accesses to the RMR). Write
the write-mode address register (WMA) with the address of the register to be read or written. Set RS(1,0)
= HL. Perform a read or write operation. The value is read from or written to the desired register. The address
register does not increment automatically. When the RMA is used for indexing, write a value 1 less than the
desired value. The RMA increments before being used as an index. The addresses of the registers
accessible by indexing are listed in the indexed access column in Table 2–4 and Table 2–5.

Color Modes
The TVP3409 provides nine different color modes that are selectable by programming control register 0 bits
CR0(7–4) (see Table 2–17).
In true color modes with multiple or fractional clocks per pixel, a clock multiplier provides the internal load
pulse that latches the data into a 16- or 24-bit pixel. True color modes bypass the look-up table and are not
gamma corrected. The modes are discussed in the following sections.
