14.0
Figure 14-1 shows how an NSE subsystem can be formed using a host ASIC and a CYNSE70256 bank. It also shows how this
NSE subsystem is integrated in a switch or router. The CYNSE70256 device can access synchronous and asynchronous SRAMs
by allowing the host ASIC to set the same HLAT parameter in all NSEs within a bank of NSEs.

The CYNSE70256 device supports the Test Access Port and Boundary Scan Architecture as specified in IEEE JTAG Standard
Number 1149.1. The pin interface to the chip consists of five signals with the standard definitions: TCK, TMS, TDI, TDO, and
TRST_L. Table 15-1 describes the operations that the test access port controller supports, and Table 15-2 describes the TAP
