8.1.1
General
The IOM-2 – SICOFI-2 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 IOM-2 – SICOFI-2 digital pins expect power supply
V
DD D
and ground GNDD are
included in the boundary scan. Depending on the pin functionality one, two or three
boundary cells are provided.
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 IOM-2 – SICOFI-2 pins are included in the following sequence in the boundary
scan:
