The pins used for interfacing the LCD Controller may be multiplexed with PIO lines. The pro-
grammer must first program the PIO Controller to assign the pins to their peripheral function. If
I/O lines of the LCD Controller are not used by the application, they can be used for other pur-
poses by the PIO Controller.
The LCD Controller is not continuously clocked. The user must first enable the LCD Controller
clock in the Power Management Controller before using it (PMC_PCER).
The LCD Controller interrupt line is connected to one of the internal sources of the Advanced
Interrupt Controller. Using the LCD Controller interrupt requires prior programming of the AIC.
The LCD Controller consists of two main blocks
and the LCD controller core (LCDC core). The DMA controller reads the display data from an
external memory through a AHB master interface. The LCD controller core formats the display
data. The LCD controller core continuously pumps the pixel data into the LCD module via the
LCD data bus (LCDD[23:0]); this bus is timed by the LCDDOTCK, LCDDEN, LCDHSYNC, and
LCDVSYNC signals.
The configuration block is a set of programmable registers that are used to configure the DMA
controller operation. These registers are written via the AHB slave interface. Only word access is
allowed.
For details on the configuration registers, see
925.
This block generates the AHB transactions. It generates undefined-length incrementing bursts
as well as 4- ,8- or 16-beat incrementing bursts. The size of the transfer can be configured in the
