JTAG Boundary Scan Register
The Boundary Scan Register (BSR) contains 303 bits
which correspond to active pins and associated control sig-
nals.
Each AT91M63200 input pin has a corresponding bit in the
Boundary Scan Register for observability.
Each AT91M63200 output pin has a corresponding 2-bit
register in the BSR. The OUTPUT bit contains data which
can be forced on the pad. The CTRL bit can put the pad
into high impedance.
Each AT91M63200 in/out pin corresponds to a 3-bit regis-
ter in the BSR. The OUTPUT bit contains data which can
be forced on the pad. The INPUT bit is for the observability
of data applied to the pad. The CTRL bit selects the direc-
tion of the pad.
