23. JTAG Boundary-scan Register
1745F–ATARM–06-Sep-07
The Boundary-scan Register (BSR) contains 256 bits which correspond to active pins and asso-
ciated control signals.
Each AT91M55800A input pin has a corresponding bit in the Boundary-scan Register for
observability.
Each AT91M55800A 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 imped-
ance.
Each AT91M55800A in/out pin corresponds to a 3-bit register in the BSR. The OUTPUT bit con-
tains data that can be forced on the pad. The INPUT bit is for the observability of data applied to
the pad. The CTRL bit selects the direction of the pad.
