TMS570LS1227: Some pins seem absent from the BSDL

Renan Santos Adriano

Hello Team,

Good day. My Customer is working with the TMS5701227CZWTQQ1, he found out that there are 188 undeclared pins. Just need to know why so many pins seem absent from the BSDL if they are not accessible via boundary Scan ?

Regards,

Hello,

The device-level boundary scan chain does not include power supplies, grounds, analog inputs, JTAG signals, and special functions such as oscillator clock input/output.

This reduces the number of terminals accessible via BSDL.
