Features

Freescale Semiconductor, Inc.

• Embedded SRAM (eSRAM)

— 100K (102,400 bytes) general-purpose internal SRAM

• Direct memory access controller (DMAC)

— Provides two memory-to-memory channels and four I/O-to-memory or memory-to-I/O

channels.

— Supports 8-bit and 16-bit FIFO and memory port size for data transfer.

— Supports modules shown in Table 1.

— Provides data transfer complete and error (burst time-out or request-out) interrupts to interrupt

controller. DMA burst length is configurable for each channel.

— Provides bus utilization control for memory channels.

— Generates DMA burst time-out error for both memory and I/O channels to terminate DMA

cycle when the burst cannot be completed in a programmed timing period.

— Generates DMA request time-out error for I/O channels to interrupt 68K core when a DMA

request is not expected during a programmed timing period.

— Supports repeat data transfer function.

— Supports block transfer function to speed up display functions such as image block movement

in LCD display, retrieval of pre-store image pattern, and window effect.

— Provides two external DMA request pins for external devices to initiate data transfer in memory

channels 0 and 1, respectively.
