A.1. About the processor signal descriptions

The tables in this appendix list the processor signals, along with their dimensions and direction, input or output, and a high-level description. Unless otherwise specified, all signals are sampled on or driven from the rising edge of the clock, CLKIN.

Many of the signal names have an m suffix, that appears before the n suffix in the case of negative sense signals. This indicates that the processor has two signals, one for each CPU, named with m being 0 or 1 for CPU0 and CPU1 respectively.

The Cortex-R5 processor has the same signals regardless of configuration. If a particular feature is not implemented, the signals associated with that feature are not used.
