NOTES:

1. Both edges of MBF2 are synchronized to the Port A clock, CKA.

2. Both edges of MBF1 are synchronized to the Port B clock, CKB.

3. There is a maximum of two CKB clock cycles of synchronization latency before MBF1

is asserted to indicate valid new mailbox data.

4. The status of mailbox flags does not prevent mailbox read or write operations.
