Known issues with the TLK2226 device:
1. ENABLE Input Signal – ENABLE signal must be held high during JTAG operation. Failure to do so will
cause data compare errors on the parallel side data path input signals. A possible solution is that a
pull-up resistor exclusively drives the ENABLE signal on the customer application board. Alternatively, the
customer must guarantee ENABLE is asserted high during JTAG operation.
