LCD glass daughterboard connectors CN6 and CN7

Two 48-pin male headers CN6 and CN7 connect the LCD glass daughterboard (MB979).
GPIOs which act as LCD glass signals and are not on CN5 and CN10 are available on these
two connectors. The space between these two connectors and the position of every LCD
glass signal is defined as a standard which allows development of common daughterboards
for several evaluation boards. The standard width between the CN7 pin1 and CN6 pin1 is
700 mils (17.78 mm).
GPIO signals on these two connectors can be tested on odd pins when the LCD glass board
is absent. Signal assignments are detailed in
Note: If CN6 and CN7 are used as GPIO extension connector on a common daughterboard, do
not connect odd pins and even pins directly onto the daughterboard, and leave Trace
connector (CN11), JTAG connector (CN16) and JP2 open.
