7.10.1 Features
7.10 LCD controller
7.11 Ethernet
The LCD controller provides all of the necessary control signals to interface directly to a
variety of color and monochrome LCD panels. Both STN (single and dual panel) and TFT
panels can be operated. The display resolution is selectable and can be up to 1024 × 768
pixels. Several color modes are provided, up to a 24-bit true-color non-palettized mode.
An on-chip 512-byte color palette allows reducing bus utilization (i.e. memory size of the
displayed data) while still supporting a large number of colors.
The LCD interface includes its own DMA controller to allow it to operate independently of
the CPU and other system functions. A built-in FIFO acts as a buffer for display data,
providing flexibility for system timing. Hardware cursor support can further reduce the
amount of CPU time needed to operate the display.
The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC
designed to provide optimized performance through the use of DMA hardware
acceleration. Features include a generous suite of control registers, half or full duplex
operation, flow control, control frames, hardware acceleration for transmit retry, receive
packet filtering and wake-up on LAN activity. Automatic frame transmission and reception
with scatter-gather DMA off-loads many operations from the CPU.
