10.5.5 Test Data Output (TDO)
The TDO pin provides an output stream of serial information from the IR chain or the DR
chains. The value of TDO depends on the current TAP state, the current instruction, and
the data in the chain being accessed. In order to save power when the JTAG port is not
being used, the TDO pin is placed in an inactive drive state when not actively shifting out
data. Because TDO can be connected to the TDI of another controller in a daisy-chain
configuration, the IEEE Standard 1149.1 expects the value on TDO to change on the
falling edge of TCK.
By default, the internal pull-up resistor on the TDO pin is enabled after reset. This assures
that the pin remains at a constant logic level when the JTAG port is not being used. The
internal pull-up and pull-down resistors can be turned off to save internal power if a High-Z
output value is acceptable during certain TAP controller states
10.5.6 Instruction register
The instruction register handles the working mode of the boundary scan cell. basically
there are three modes. BYPASS, SAMPLE/PRELOAD and EXTEST. According to the
standard also the definition of further commands are allowed. The CLRC663 Boundary
scan interface has Clamp and HighZ as additional instructions.
10.5.7 Data register
According to the IEEE1149.1 standard there are two types of data register defined:
bypass, boundary scan
The bypass register enable the possibility to bypass a devise when part of the scan path.
The boundary scan register is the chain of the boundary cells. The size of this register can
differ per device, in the CLRC663 it has the size of 8 bits.
10.5.8 Boundary scan cell
The boundary scan cell opens the possibility to control a hardware pin independent of its
normal usecase. Basically the cell can only do one of the following: control, output and
Input.
10.5.9 Boundary scan path
This chapter shows the boundary scan path of the CLRC663.
