Nexus reset is different than system reset; MDO 1-11 are enabled when trace (RPM or FPM) is enabled, and MDO 12-15 when FPM trace is enabled. MSEO and MCKO

are also dependent on trace (RPM or FPM) being enabled.

The Nexus pins don’t have a “primary” function as they are not configured by the SIU. The pins are selected by asserting JCOMP and configuring the NPC. SIU values

have no effect on the function of these pins once enabled.

MCKO is disabled from reset; it can be enabled from the tool (controlled by Nexus NPC_PCR register).

Do not connect pin directly to a power supply or ground.
