Abstract

In a JTAG test and debug environment, the parameters that are accessed by command include a delay parameter. The delay parameter prevents the subsequent command from being executed until both the original command has been executed and the clock cycles indicated by the delay parameter have been completed. Because the time delay is included as a parameter identified by the command, the delay parameter can be programmed.
