SYSCTL#24

Modules may not be ready for access if their power domains are first turned off and then on

Description

There are five modules (CAN, Ethernet MAC, Ethernet PHY, USB and CCM) on the device that reside in a separate power domain. These modules can be turned off of their power domains to save additional leakage currents. When the power domains are turned off and later turned on, the modules can indicate not ready for access indefinitely when polled on their respective Peripheral Ready Register such as PRUSB register.

Workaround

None. Do not turn off power domains.
