4.0 Embedded Controller Modules
Block Length Counter Register (BLTCn)
A double-word, read/write register. Holds the current number of DMA transfers to be executed in the current block. BLTCn
is decremented by one after each transfer cycle. A DMA transfer may consist of one or two bytes according to TCS bit in
DMACNTLn register.
Location: Channel 0 - 00 FA10
Type:
Note: Writing 0 to Block Length Counter field of BLTCn initializes the DMA for 2
Block Length Register (BLTRn)
A double-word, read/write register. Holds the number of DMA transfers to be executed in the next block. Writing this register,
sets VLD bit in DMASTATn register to 1.
Location: Channel 0 - 00 FA14
Type:
Note: Writing 0 to Block Length field of BLTRn initializes the DMA for 2
DMA Control Register (DMACNTLn)
A word-wide, read/write register that synchronizes the channel’s operation with the programing of the block transfer param-
eters. On reset, the implemented bits are initialized to 0.
The format of the DMACNTLn register is shown below.

CHEN (Channel Enable). This bit must be set to enable DMA operation on this channel
0: Channel disabled (default)
1: Channel enabled
If CHEN bit in DMACNTLn register is cleared in all channels, the DMA clock is disabled to preserve power.
