SEQUENTIAL LATCHING DEVICE WITH ELEMENTS TO INCREASE HOLD TIMES ON THE DIAGNOSTIC DATA PATH |
摘要 |
A latching device includes input and output latching elements to receive and output data values wherein the input and output elements are configured to receive a first and second clocks, respectively. The clocks have the same frequency but are inverted. The elements are transparent and transmit data between an input and an output in response to the first value of a received clock and are opaque and hold the data value in response to a second value of the received clock, such that in response to the first and second clocks the input data value is clocked through the input and output elements to the output. The device includes a device for selecting an operational data value or a diagnostic data value for input to the input element in response to a value of a diagnostic enable signal indicating a functional mode or a diagnostic mode. |
