Section 21 Port Integration Module (PIM) Block Description
Consult the PIM_9DTB128 Block User Guide for information about the Port Integration Module.
Section 22 Voltage Regulator (VREG) Block Description
Consult the VREG Block User Guide for information about the dual output linear voltage regulator.
Section 23 Printed Circuit Board Layout Proposal
The PCB must be carefully laid out to ensure proper operation of the voltage regulator as well as of the
MCU itself. The following rules must be observed:
Freescale Semiconductor
•
•
Every supply pair must be decoupled by a ceramic capacitor connected as near as possible to the
corresponding pins (C1 – C6).
Central point of the ground star should be the VSSR pin.
