ARM DDI 0029G
Pullup resistors
The IEEE 1149.1 standard implies that nTRST, TDI, and TMS must have internal
pullup resistors. To minimize static current draw, these resistors are not fitted to the
ARM7TDMI core. Accordingly, the four inputs to the test interface, the nTRST, TDI,
and TMS signal plus TCK, must all be driven to good logic levels to achieve normal
circuit operation.
