JTAG INTERFACE
support the JTAG boundary scan interface. The IDT72V3640/72V3650/
72V3660/72V3670/72V3680/72V3690 incorporates the necessary tap con-
troller and modified pad cells to implement the JTAG facility.

TEST ACCESS PORT (TAP)
internal of the processor. It consists of four input ports (TCLK, TMS, TDI, TRST)
and one output port (TDO).
