A variety of TSC695F test and diagnostic hardware functions, including boundary scan,
internal scan, clock control and On-chip Debugger, are controlled through an IEEE
1149.1 (JTAG) standard Test Access Port (TAP).
The TAP interfaces to the JTAG bus via 5 dedicated pins on the TSC695F chip. These
pins are:
•
•
•
•
•
Five standard instructions are supported by the TSC695F TAP.
The design is highly testable with the support of an On-Chip Debugger (OCD), an inter-
nal and boundary scan through JTAG interface.
