The third column in the table lists the accessibility of the register: read-only, write-only,

read/write.

All AHB register write transactions except for accesses to the interrupt registers are

posted i.e. the AHB transaction will complete before write data is actually committed to the

register. Accesses to the interrupt registers will only be completed by accepting the write

data when the data has been committed to the register.

7.1 Ethernet MAC register definitions

This section defines the bits in the individual registers of the Ethernet block register map.

RSV 0xFFE0 0160 RO Receive status vector register.
- 0xFFE0 0164 to

FlowControlStatus 0xFFE0 0174 RO Flow control status register.
- 0xFFE0 0178 to
0xFFE0 01FC - Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit
is not defined.
