Revision 6.01 - EPSON CONFIDENTIAL
Come out of reset - all registers set to default values
enter sleep mode (or use PWRSVE pin)
set PLL M-Divider.
CLKI = 12MHz,
PLL input clock = CLKI/12 = 1.0MHz.
LL = 45, resulting SYSCLK = LL x PLL input clock = 45MHz
set PCLK divide, PCLK = 22.5MHz
set SYSCLK source = PLL
no panel data swap, 18-bit panel
HDP = 800 pixels
HNDP = 20 pixels
VDP = 480 lines
VNDP = 6 lines
HS Pulse Width = 20 pixels
HS Start Position = 45 pixels
VS Width = 2 lines
VS Start Position (VFP) = 1 line
PCLK Polarity: data output on falling edge
set memory to 16 bpp,
set input data mode to RGB 5:6:5
disable sleep mode
wait for PLL to lock - poll REG[04h] bit 7
Window X Start Position = 0
Window Y Start Position = 0
