Keypoints:
 Mask Channel
Data in the Mask Channel can be edited in the user space. “0” in the Mask
Channel, indicates the corresponding Tri-state Channel output is not high Z
(normal output), while “1” indicates the corresponding Tri-state Channel
output is high Z.
 Tri-state Channel
Tri-state Channel is the channel to be “masked”. The Tri-state Channel output
depends on the corresponding data “1” and “0” in Mask Channel, high Z, and
not high Z respectively.
Example:
Suppose D0 is the Mask Channel, D1 and D5 are Tri-state Channels. Set data in the
three channels as shown below:
D0: 1 0 0 1 1 0 0 1 0 1 0 1 0 1 0 0 0 0 1 0 0 1 0 0 …
D1: 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 …
D5: 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 …
