30 / 146 page  Qorivva MPC5645S Microcontroller Data Sheet, Rev. 8 30 Freescale Semiconductor 2.4.4 Nexus pins On the 176 LQFP and the 208 LQFP package options a reduced set of Nexus pins are optionally available, multiplexed with GPIO pins. On the 416 TEPBGA package option all Nexus pins are dedicated to Nexus only. NMI Non-Maskable Interrupt I/O S Input, none 45 53 AC7 VRC_CTRL Voltage Regulator external NPN Ballast base control pin Analo g — 29 29 AA3 VREF_ RSDS2 RSDS interface reference voltage Analo g — — 145, 165 J24,D24 VREG_ BYPASS3 Pin used for factory testing I — — 26 26 AA2 1 Reset configuration is given as I/O direction and pull direction (for example, “Input, pullup”). 2 Although this signal is not a supply for RSDS pads, it needs to be terminated in an external capacitor with a value of 47 pF. 3 VREG_BYPASS should be connected to ground during normal operation.
