Peripheral Bus Errors; Timing Examples - Analog Devices ADSP-BF506F Hardware Reference Manual

Peripheral Bus Errors

The SPORT generates a peripheral bus error for illegal register read or
write operations. Examples include:
• Reading a write-only register (for example,
• Writing a read-only register (for example,
• Writing or reading a register with the wrong size (for example,
32-bit read of a 16-bit register)
• Accessing reserved register locations

Timing Examples

Several timing examples are included within the text of this chapter (in the
sections "Framed Versus Unframed" on page
Frame Syncs (Normal Versus Alternate Timing)" on page
"Frame Syncs in Multichannel Mode" on page
tains additional examples to illustrate other possible combinations of the
framing options.
These timing examples show the relationships between the signals but are
not scaled to show the actual timing parameters of the processor. Consult
the ADSP-BF504, ADSP-BF504F, ADSP-BF506F Embedded Processor
Data Sheet for actual timing parameters and values.
These examples assume a word length of four bits (
