Advisory May 1999 Clarification to the Serial I/O Control Register Description for the DSP1620/27/28/29 Devices Active Clock Frequency The purpose of this advisory is to clarify the function of the serial I/O control registers in the DSP1620/27/28/29 devices. Specifically, it clarifies the function of the control register field that specifies the active clock frequency. The device data sheets state that the active clock frequency is a ratio of the input clock frequency on the CKI pin (DSP1627/28/29 devices) or the output clock frequency on the CKO pin (DSP1620 device).
