The Data Register in the Boundary Scan path is an 87-bit shift register. The Boundary DR provides control and
observability of all the device pins as well as the SFR bus and Weak Pullup feature via the EXTEST and SAMPLE
commands.
EXTEST provides access to both capture and update actions, while Sample only performs a capture.
