Example
For a monochrome STN LCD, 4-bit interface panel, 4 pixels are captured by the
panel in every panel clock cycle. Figure 14.8 gives the major registers to be
programmed for supporting 4-bit interface STN LCD. LCLK and Refresh rate are
examples only. And LSWC, LEWC, LPW, and FEWC are STN LCD panel
dependent.
LCLK = 20 MHz, Refresh rate = 60 Hz
PXDW* = 0 (4bits)
VD* = 1
BPP* = 2 (4bpp)
DP* = 0 (one pixel data per pixel clock cycle)
NI = 1
TV* = 0, TFT* = 0, STN* = 1
LSWC* = LEWC* = LPW* = FEWC* = 1 (STN LCD dependent)
