troller is a state machine controlled by the TCK and TMS signals. The TAP Controller selects
either the JTAG Instruction Register or one of several Data Registers as the scan chain (shift
register) between the TDI-input and TDO-output. The Instruction Register holds JTAG instruc-
tions controlling the behavior of a Data Register.
The ID Register, Bypass Register, and the Boundary-Scan Chain are the Data Registers used
for board-level testing. The Reset Register can be used to keep the device reset during test or
programming.
The Service Access Bus (SAB) interface contains address and data registers for the Service
Access Bus, which gives access to on-chip debug, programming, and other functions in the
device. The SAB offers several modes of access to the address and data registers, as dis-
cussed in
