9 _{This signal name includes eTPU_C functionality that this device does not have. This is for forward compatibility with devices that have an eTPU_C.}
10 _{During and just after POR negates, internal pull resistors can be enabled, resulting in as much as 4 mA of current draw. The pull resistors are disabled when}
the system clock propagates through the device.
11 _{NMI does not have a PCR PA configuration; it is enabled when NMI is enabled through the SIU_IREER and SIU_IFEER registers.}
12 _{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.
13 _{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.
14 _{MCKO is disabled from reset; it can be enabled from the tool (controlled by Nexus NPC_PCR register).}
15 _{Do not connect pin directly to a power supply or ground.}
