•

DMA Channel 10 Block Size Limit Counter

•

block size of DMA channel 10 (bytes)

− Unlimited block size (block size =

∞ ):

bit[11:0] of the DMA10BlockSize register = 000h

− Limited block size (block size = 1 - 4095)

•

The Block Size counter will decrement regardless of the DMA Address counter’s activity. The block size

•

Writing to this register will also clear the DMA channel 10 interrupt.

Bit 15:

Channel 10 Enable is cleared when the block size limit is reached, and must be set, (enabled) after a

new block size is entered. The new block size can only be written

when this bit is 0.
