 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-sate
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,
