10.3.1 Boundary Scan
General
The SICOFI-4 provides fully IEEE Std. 1149.1 compatible boundary scan support
consisting of:
– a complete boundary scan (digital pins)
– a test access port controller (TAP)
– four dedicated pins (TCK, TMS, TDI, TDO)
– a 32 bit ICODE register
All SICOFI-4 digital pins expect power supply VDDD and ground GNDD are included in
the boundary scan. Depending on the pin functionality one, two or three boundary cells
are provided.

I/O
When the TAP controller is in the appropriate mode, data is shifted into/out of the
boundary scan via the pins TDI/TDO controlled by the clock applied to pin TCK.
The SICOFI-4 pins are included in the following sequence in the boundary scan:
