24.1. Boundary Scan
The DR in the Boundary Scan path is an 134-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.
266
EXTEST provides access to both capture and update actions, while Sample only performs a capture.
