DSP56305 Overview
Manual Organization
SECTION 5—GENERAL PURPOSE INPUT/OUTPUT (GPIO)
– Describes the DSP56305 General Purpose Input/Output (GPIO) capability and
the programming model for the GPIO signals (operation, registers, and
control)
SECTION 6—HOST INTERFACE (HI32)
– Describes the 32-bit Host Interface (HI32), including a quick reference to the
HI32 programming model
SECTION 7—ENHANCED SYNCHRONOUS SERIAL INTERFACE (ESSI)
