Functional Analysis
The OCP micro-controller reads the program directly from the FLASHROM via one
of its I/O ports. The display portion of the ROM can also be read by the micro-con-
troller and fed directly into the Liquid Crystal Display interface.
2.5.3 Liquid Crystal Display (LCD)
The display used on the Avantra is a 320 x 240 bit LCD. The display includes a
character generator for a 6 x 12 bit character as well as a graphical interface for the
icons stored in FLASHROM. The LCD connects to the OCP module via a 20-pin flex
cable.
The viewing angle of the LCD is user adjustable under software control. An 8-bit
word is written to a DAC which is proportional to the LCD's optimum viewing
angle.
2.5.4 Keypad
The keypad is set up in a 6 x 5 matrix of rows and columns. A key stroke is deter-
mined by clearing a column signal and reading the row to determine the active key
stroke
2.5.5 OLP/Bridge Interface

2.5.6 Speaker (Audio Interface)
