25.1. 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.
342
EXTEST provides access to both capture and update actions, while Sample only performs a capture.
