Power and Ground Supply Summary

6 Port A[14:15]—EXTAL32 and XTAL32 functions only apply on the 144LQFP. These functions are on PortK[0:1] for the 176LQFP and

208BGA. In the 176 LQFP and 208 BGA packages, activity on PA14 should be minimized if the 32kHz XTAL is enabled.

7 This analog input pin has reduced analog-to-digital conversion accuracy compared to PA0–PA15. See the MPC5510 Microcontroller

Family Data Sheet for values.

8 The NEXUS function is selected when the JTAG TAP controller is enabled via the JCOMP pin and the appropriate bits in the NP

PCR register. The value of the PA field in the associated PCR register has no effect on the pin function when the NEXUS function

is selected.

9 Pullup is enabled only when JCOMP is negated.

10 Always connect the TEST pin to Ground (Vss).
