Section 18 Ethernet Controller (EtherC)
18.3.1
ARSTR resets all modules (EtherC and E-DMAC) related to the Ethernet. By writing 1 to the
ARST bit in ARSTR, a software reset is issued to all modules related to the Ethernet (for 64 cycles
at external bus clock Bφ). The ARST bit is always read as 0. While a software reset is issued,
register access to all modules related to the Ethernet is prohibited.

These bits are always read as 0. The write value
should always be 0.
Software Reset
When written with 1, a software reset is issued to all
modules related to the Ethernet (for 64 cycles at
external bus clock Bφ).
Writing 0 does not affect this bit. This bit is always read
as 0.
While a software reset is issued, register access to all
modules related to the Ethernet is prohibited. The
following registers are not initialized by a software
reset.
