instruction code for EXTEST is different. The data shifted out of TDO consists of the data
that was present in the capture registers after the capture phase. New test data shifted
into the TDI pin appears at the TDO pin after being clocked through the entire
boundary-scan register.
You can activate BYPASS instruction mode with an instruction code made up of only
ones.
controller is in the SHIFT_DR state. In this state, data signals are clocked into the bypass
register from TDI on the rising edge of TCK and out of TDO on the falling edge of the
same clock pulse.
Use IDCODE instruction mode to identify the devices in an IEEE Std. 1149.1 chain.
When you select IDCODE, the device identification register loads with the 32-bit
vendor-defined identification code. The device ID register is connected between the
TDI and TDO ports and the device IDCODE is shifted out.
IDCODE instruction mode for MAX V devices are listed in the
Programmability in MAX V Devices
