NOTES:
1. These input pins may be sampled on either the rising or falling edge of the memory clock.
2. These output pins may be driven on either the rising or falling edge of the memory clock.
3. The LCD data pins can be programmed to be driven on either the rising or falling edge of the pixel clock
(L_PCLK).
4. These LCD signals can, at times, transition when L_PCLK is not clocking (between frames). At this time,
they are clocked with the internal version of the pixel clock before it is driven out onto the L_PCLK pin.
5. These signals are PCMCIA outputs and are driven by a state machine clocked by BCLK. The user defines
BCLK by programming the number of processor clocks per BCLK. Two processor clocks make one
memory clock cycle. To ensure proper operation, the user must adhere to the protocol description.
