JTAG Interface
14
The R4000 processor provides a boundary-scan interface that is
compatible with Joint Test Action Group (JTAG) speciļ¬cations, using the
industry-standard JTAG protocol.
This chapter describes that interface, including descriptions of boundary
scanning, the pins and signals used by the interface, and the Test Access
Port (TAP).
