Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-0
STA<15:0>: Primary DMA RAM Start Address bits (source or destination)
Note 1: A read of this address register returns the current contents of the DMA RAM Address register, not the con-
tents written to STA<15:0>. If the channel is enabled (i.e., active), writes to this register may result in
unpredictable behavior of the DMA channel and should be avoided.

STB<15:0>: Secondary DMA RAM Start Address bits (source or destination)
Note 1: A read of this address register returns the current contents of the DMA RAM Address register, not the con-
tents written to STB<15:0>. If the channel is enabled (i.e., active), writes to this register may result in
unpredictable behavior of the DMA channel and should be avoided.
