Detailed Description

Macro Definition Documentation

◆ GMAC_ADDRESS_MASK

#define GMAC_ADDRESS_MASK   ((unsigned int)0xFFFFFFFC)

The buffer addresses written into the descriptors must be aligned so the last few bits are zero. These bits have special meaning for the GMAC peripheral and cannot be used as part of the address.
