the range available is from 1bps to 60Mbps.
 Press CSLevel to select L or H, wherein, L represents low level and H
represents high level.
3. IIC Protocol Setting

 Press Mask Chan to select the data of any channel (D0~D15) as the
tri-state mask of data output. “None” represents that no mask channel is set.
The data of the mask channel (D0~D15) is from the data editing area (refer
to “User Data Editing”). In data editing area, starting from the address
00000000, every two addresses store 16bits data (corresponding to D0~D15
of the mask channel). For example, for the data “0008”, 0x08 represents
D7~D0 and 0x00 represents D15~D8.The data “0” in the mask channel
indicates that the data of the corresponding bit in tri-state channel is output
normally while “1” indicates the output of the corresponding bit in tri-state
channel is high Z (Z).
 Press Tri-state Chan to select one or more channels (D0~D15) as the
tri-state channels. “None” represents that no tri-state channel is set.
Tri-state Channel is the channel to be “masked” and the data of the tri-state
channel is “masked” with the data of the mask channel for output. Whether
the output of the tri-state channel is high Z or not depends on whether the
data of the corresponding bit in the mask channel is “1”.
For example,
