Abstract
A boundary scan controller and method. The boundary scan controller generates an output clock for shifting output data to a target device as a serial stream. The boundary scan controller generates another clock for receiving a serial stream of input data from the target device. The input clock is generated after the output clock according to a predetermined delay. The predetermined delay provides a period of time for the target device to respond to the serial stream of output data. The boundary scan controller comprises a clock generator for generating a system clock, a transmit module having a transmit clock generator and an output data register, a receive module having a receive clock generator and an input data register, and a state machine controller. The receive module includes a delay counter for generating a delay between the transmit and receive data clocks.
