Microcontroller
MPC5xx
The AMI module accepts only 16-bit wide (word) transactions. It does not have byte select lines
and, thus, does not recognize 8-bit wide accesses. Therefore, it does not indicate errors in the event
of 8-bit transactions.
The WE# signal indicates the direction of data transfer for a transaction.
The OE# signal enables the AMI data output to a microcontroller during read transactions.
INT_CC# is an interrupt line that can be used for requesting, by means of the internal interrupt
controller, a service routine from a host controller.
The MFR4200 AMI module does not support burst transactions.
