... IEEE 1149.1 Serial Boundary Scan (JTAG) The CY7C1370D/CY7C1372D incorporates a serial boundary scan test access port (TAP). This part is fully compliant with 1149.1. The TAP operates using JEDEC-standard 3.3V or 2.5V I/O logic levels. The CY7C1370D/CY7C1372D contains a TAP controller, instruction register, boundary scan register, bypass register, and ID register ...
