JTAG Boundary-scan Register
The Boundary-scan Register (BSR) contains 484 bits that correspond to active pins and associ-
ated control signals.
Each AT91SAM9261 input/output pin corresponds to a 3-bit register in the BSR. The OUTPUT
bit contains data that can be forced on the pad. The INPUT bit facilitates the observability of data
applied to the pad. The CONTROL bit selects the direction of the pad.
