6.19.2 SUPPORTED LCD CONTROLLERS
The following table lists LCD controllers supported by the LPC47S45x and their corresponding signals. Chip select 1,
XCS1, is active high to support these LCD controllers without any external logic.
The two least significat address bits are used to communicate the type and direction of a transaction
initiated with the LCD controller. A1 determines if the transaction is a command or data type and A0
determines is the transaction is a read/write.
Note: The direction of LCD Controller Operation (i.e. Read/Write) must match the direction of the command issued by
either the LPC interface or the SMBus.
Timing for SMBus initiated cycles accessing the LCD controller are shown in the Timing Diagrams section.
