DBCK0/OS01/DSP0_GPIO9

I/O

Debug Port Bit Clock/Chip Status 1 (Input/Output)/General

Purpose I/O (Input/Output). The serial clock for the Debug Port is

provided when an input. When an output, together with OS0

provides information about the chip status. Optionally it can be

used as a general purpose I/O.
