The boundary scan register contains bits for all device signal and clock pins and associated control signals.
Bidirectional pins include a single scan bit for data (IO.Cell) as shown in
controlled by an enable cell, shown in
bidirectional pin is an input or an output. One or more bidirectional data bits can be serially connected to
a control bit as shown in
interpreted only after examining the I/O control bit to determine pin direction.
Open-drain bidirectional bits require separate input and output cells as no direction control is available
from which to determine signal direction. Programmable open-drain signals also have an enable cell
(XXX.de) to select whether the pin is open drain or push-pull. Signals with pull-up or pull-down resistors
have an associated enable cell (XXX.pu); one enable cell can control multiple resistors.
