2.3.1
The MTSXL provides fully IEEE Std. 1149.1 compatible boundary scan support
consisting of
– a complete boundary scan
– a test access port controller (TAP controller)
– four dedicated pins (TCK, TMS, TDI, TDO)
– a 32 bit IDCODE register
All pins except power supply and ground are included in the boundary scan. Depending
on the pin functionality one, two or three boundary scan 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 using the 6.25 MHz clock on pin TCK.
The MTSXL pins are included in the boundary scan in the following sequence:
