1
Tested at room temperature with CPU polling a status register. All clocks were off except the UART and CFM (when
running from flash memory).
2
Peak current measured with all modules active, and default drive strength with matching load.
3
Due to the errata “Non-functional RAM Standby Supply” in the
MCF5213 Device Errata
, V
STBY
should be connected
directly to V
DD
and cannot be used for RAM standby operation.
