Question:
What are the default JTAG pin states on a USB-Serial CY7C65215/CY7C65215A device?
Answer:
CY7C65215/CY7C65215A supports a 5-pin JTAG in master mode for code flashing at 400 kHz.
Note that JTAG on SCB1 cannot simultaneously operate with I2C, SPI, or UART on SCB0.
Table 1 lists the JTAG pin configurations and their default states.
