The boundary scan TAP is a standard 1149.1 compliant TAP and can be used for
XCore, Switch and OTP for such actions as loading code and debugging. Both TAPs
which optionally add in additional TAPs into the JTAG chain for each of the Switch,
XCore and OTP. The XCore TAP allows register read/write commands to be made for
A diagram of the JTAG chain structure is shown below:
The JTAG device identification register can be read by using the IDCODE instruction.
boundary scan of the I/O pins of the device. The chip TAP allows access into the
have a bypass register, an instruction register length of 4, a data register length of
32 and a TDO register. From reset, the chip TAP is in BYPASS so simply presents an
extra 1-bit into the scan chain when shifting data.
If access to the XCore/Switch/OTP is required, the ChipTAP sets internal multiplexers
