DSP56309 Overview
1.2 Manual Conventions
This manual uses the following conventions:
1-2
Notes: 1.
Chapter 7, Enhanced Synchronous Serial Interface (ESSI). Enhancements, data and
control signals, programming model, operating modes, initialization, exceptions, and
GPIO.
Chapter 8, Serial Communication Interface (SCI). Signals, programming model,
operating modes, reset, initialization, and GPIO.
Chapter 9, Triple Timer Module. Architecture, programming model, and operating modes
of three identical timer devices available for use as internals or event counters.
Appendix A, Bootstrap Code. Bootstrap code and equates for the DSP56309.
Appendix B, Programming Reference. Peripheral addresses, interrupt addresses, and
interrupt priorities for the DSP56309; programming sheets listing the contents of the
major DSP56309 registers for programmer’s reference.
Bits within registers are always listed from most significant bit (MSB) to least significant
bit (LSB).
Bits within a register are indicated AA[n – m], n > m, when more than one bit is involved
in a description. For purposes of description, the bits are presented as if they are
contiguous within a register. However, this is not always the case. Refer to the
programming model diagrams or to the programming sheets to see the exact location of
bits within a register.
When a bit is “set,” its value is 1. When a bit is “cleared,” its value is 0.
The word “assert” means that a high true (active high) signal is pulled high to V
a low true (active low) signal is pulled low to ground. The word “deassert” means that a
high true signal is pulled low to ground or that a low true signal is pulled high to V

PIN is a generic term for any pin on the chip.
Ground is an acceptable low voltage level. See the appropriate data sheet for the range of acceptable low
voltage levels (typically a TTL logic low).
