Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15
CHEN: Channel Enable bit
1
= Channel enabled
0
= Channel disabled
bit 14
SIZE: Data Transfer Size bit
1
= Byte
0
= Word
bit 13
DIR: Transfer Direction bit (source/destination bus select)
1
= Read from DMA RAM address, write to peripheral address
0
= Read from peripheral address, write to DMA RAM address
bit 12
HALF: Early Block Transfer Complete Interrupt Select bit
1
= Initiate block transfer complete interrupt when half of the data has been moved
0
= Initiate block transfer complete interrupt when all of the data has been moved
bit 11
NULLW: Null Data Peripheral Write Mode Select bit
1
= Null data write to peripheral in addition to DMA RAM write (DIR bit must also be clear)
0
= Normal operation
bit 10-6
Unimplemented: Read as ‘0’
bit 5-4
AMODE<1:0>: DMA Channel Operating Mode Select bits
11
= Reserved (will act as Peripheral Indirect Addressing mode)
