38.10.14 LCD FIFO Register
Name: LCDFIFO
Address:0x00600814
Access: Read-write
Reset value: 0x0000000
• FIFOTH: FIFO Threshold
Must be programmed with:
where:
6062M–ATARM–23-Mar-09
• 512 is the effective size of the FIFO. It is the total FIFO memory size in single scan mode and half that size in dual scan
• DMA_burst_length is the burst length of the transfers made by the DMA. Refer to
mode.
FIFOTH = 512 - (2 x DMA_BURST_LENGTH + 3)
