DSP56F826 Preliminary Technical Data
Clock Output—This pin outputs a buffered clock signal. By programming
the CLKO Select Register (SLKOSR), the user can select between
outputting a version of the signal applied to XTAL and a version of the DSP
master clock at the output of the PLL. The clock frequency on this pin can be
disabled by programming the CLKO Select Register (CLKOSR).
Data Bus— D0–D15 specify the data for external program or data memory
accesses. D0–D15 are tri-stated when the external bus is inactive.
Debug Event—DE provides a low pulse on recognized debug events.
Data Memory Select—DS is asserted low for external data memory access.
