IEEE 1149.1 Serial Boundary Scan (JTAG) The CY7C1471BV25, CY7C1473BV25, and CY7C1475BV25 incorporate a serial boundary scan Test Access Port (TAP). This port operates in accordance with IEEE Standard 1149.1-1990 but does not have the set of functions required for full ...
Page 15
TAP Registers Registers are connected between the TDI and TDO balls and enable the scanning of data into and out of the SRAM test circuitry. Only one register is selectable at a time through the instruction register. Data is serially ...
Page 16
Repeatable results may not be possible. To guarantee that the boundary scan register captures the correct signal value, make certain that the SRAM signal is stabilized long enough to meet the ...
