MCF5271 Reference Manual Addendum
Errata and corrections for the MCF5271 Reference Manual, detailing pinout changes, register field updates, and core frequency improvements from 100MHz to 150MHz.
Overview
This reference manual addendum (MCF5271RMAD) provides technical corrections and updates for the MCF5271 ColdFire microcontroller documentation across revisions 1, 1.1, and 2. Key changes include the clarification that only one interrupt controller is present, pin assignment corrections for the 160QFP package (such as SD_CKE and QSPI_CS1), and updated reset values for various registers including ACR and CACR. The document also notes an improvement in core frequency from 100MHz to 150MHz and provides specific software workarounds for the Fast Ethernet Controller (FEC) to prevent duplicate frame transmission.
Use Cases
- Verifying pinouts for 160QFP hardware design
- Configuring interrupt priority and level assignments
- Implementing FEC software drivers to manage transmit buffer descriptors
- Correcting register configurations for cache and RAMBAR settings
