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.
The JTAG usercode register can be read by using the USERCODE instruction. Its
have an instruction register length of 4. 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
program loading/debug.
