12.5.4.1
6120H–ATARM–17-Feb-09
JTAG Boundary-scan Register
with a non-JTAG chip ID that identifies the processor to the ICE system. This is not IEEE 1149.1
JTAG-compliant.
It is not possible to switch directly between JTAG and ICE operations. A chip reset must be per-
formed after JTAGSEL is changed.
A Boundary-scan Descriptor Language (BSDL) file is provided to set up test.
The Boundary-scan Register (BSR) contains 187 bits that correspond to active pins and associ-
ated control signals.
Each AT91SAM7X 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.
