JTAG Boundary-scan Register
6071A–ATARM–28-Oct-04
A Boundary-scan Descriptor Language (BSDL) file is provided to set up test.
The Boundary-scan Register (BSR) contains 96 bits that correspond to active pins and associ-
ated control signals.
Each AT91SAM7S32 input/output pin corresponds to a 3-bit register in the BSR. The OUT-
PUT 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.
