TDI, TMS, TRST and L3DATA not driven; TC0 and TC1 driven HIGH; all other inputs driven LOW.
Inputs TRST, TCK, TMS and TDI are TTL level compatible; all other inputs are CMOS level compatible.
Input TRST (pin 38) should be connected to ground for normal operation and connected to V
DD
for boundary scan
testing.
