[CPU-3.5] The CPU Crashes When the Clock Frequency Switches

Affected revisions: v0.0

Description

The CPU crashes when the clock frequency switches directly from 240 MHz to 80/160 MHz

Workarounds

When switching frequencies, use intermediate frequencies as follows:

1. 2 MHz <-> 40 MHz <-> 80 MHz <-> 160 MHz

2. 2 MHz <-> 40 MHz <-> 240 MHz

Solution

Fixed in chip revision v1.0.
