5.2.5. Main LCD
A 128 x 128 pixel graphical display is used to give maximum information.
It can display Chinese and large character sets.
The HD66782 display driver is used. This driver has Display RAM.
LCD glass size is as follows.
The display driver is controlled by setting command register and display data registers.
To send data or command to display driver, nCS; provided from companion IC; is used for chip select.
These registers are assigned as follows.
Command register: $01C0:0000
Data register: $01C1:0000
These registers are write access only.
5.2.6. IrDA
The IrDA module is mounted on the upper unit PCB. EB-X400 supports IrDA file transfer and object exchange, but does not
support IrDA dial-up.
In a special asynchronous mode of U2001 (E-Gold+ V3), the ASC supports IrDA data transmissions up to 115.2 KBaud with
fixed or programmable IrDA pulse width. An autobaud detection unit detects asynchronous data frames with its baudrate and
mode, with automatic initialization of the baudrate generator and the mode control bits.
