Qorivva MPC5xxx/SPC5xx Debugger and NEXUS Trace

NEXUS.PINCR
Define DCI PINCR register value
When this command is called with a value, the specified value is written to the DCI_PINCR register every
time the debugger connects to the processor (SYStem.Up, Attach, Go, StandBy). The meaning of the
individual bits, and the existence of this register in general, depends on the target processor.
Example for SPC570S:
NEXUS.PortMode
Set NEXUS trace port frequency
Sets the NEXUS trace port frequency. For parallel NEXUS, the setting is the system clock divider. For Aurora
NEXUS, the setting is a fixed bit clock which is independent of the system frequency.

NOTES:
Parallel NEXUS: The settings 1/1 and 1/3 is not supported by all processors.
Check the processor reference manual if this is a valid mode for your processor.
Parallel NEXUS: Please check in the processor’s data sheet if the NEXUS trace
port of your processor is functional at the selected system frequency and
MCKO divider. Current silicon versions allow trace port frequencies up to
60~80 MHz.
