C.18 AD Channel n DATA- Read BASE+30,32
AD Channel n DATA (n = 0 or 2)
BASE + 30, 32
are for four channels DMA data transfer. Data transfer
will alternate from CH0 + CH1 to CH2 + CH3 automatically. The format
is the same as
BASE + 0, 2 or BASE + 4, 6
. CH0 + CH1 is first 32-bit,
CH2 + CH3 is the second and CH0 + CH1, …and so on. User only want
to transfer CH0 + CH1, please use
BASE + 0, 2
, transfer CH2 + CH3,
please use
BASE + 4, 6
. About DMA data transfer, please refer to
PCI9056 datasheet.
DMA data transfer support 1, 2 or 4 channels data acquisition.
For 1 channel data acquisition, only channel 0 or 2 is acceptable. For 2
channels data acquisition, only channel 0,1 or 2,3 is acceptable.
The DMA data transfer to memory format are list as below:
1. One channel CH0
