Hi,
I need to programmatically read register IF_STATUS (offset 0x304) of the Frame Manager EMAC3 that should be at address 0x1AE4304. Of this register only the nibble 16-19 is meaningful because the other bits are reserved. The value of the nibble that I read is 0xD (or 0b1101) that seems correct because the bits indicate:
- a valid link is established by the RGMII PHY
- 1 Gbps
- RGMII full duplex link is established
What it looks weird to me is that the full 32-bit value I read is:
0x00D00000
i.e. the 0xD nibble does not appear to be in the right position because it occupies bits 20-23. Changing the endianity by byte swapping does not help because in this case the value would be
0x0000D000
and the nibble would occupy bits 12-15
What am I doing wrong here?
Thanks in advance for the support
