Functional Description
AT91RM9200
APB
ASB
The Ethernet Media Access Control (EMAC) engine is fully compatible with the IEEE 802.3
Ethernet standard. It manages frame transmission and reception including collision detection,
preamble generation and detection, CRC control and generation and transmitted frame padding.
The MAC functions are:
• Frame encapsulation and decapsulation
• Error detection
• Media access management (MII, RMII)
