I/O
O
Flat Panel VEE This is used to control the bias power to the
panels
O
Flat Panel Backlight This is used to control the backlight power
to the panels or as a General Purpose Output Pin as defined by
register CR2F bits 3&2
O
Panel data These pins are used to provide the data interface to
different kinds of panels. The following table shows the functions
of these pins based on the selected panel type
I/O
LCD_ID[3..0] pins are general purpose read only bits which can
be used for panel identification. During RESET# these LCD_ID
I/O
pins are inputs. The state of these bits are reflected in register
CR2Eh bits 3:0. The state of these bit can also be sampled
I/O
anytime on-the-fly through register GR17 bit-3. Internally these
pins are pulled-up, recommended external pull down resistor
I/O
value is 22k ohm
O
CRT Vertical Sync This output is the vertical synchronization
T/S
pulse for the CRT monitor
O
CRT Horizontal sync This output is the horizontal
T/S
synchronization pulse for the CRT monitor
