*Note: In case of 64pin package, the PHY mode is must be set by PHYCONF SFR. So, user must
set the MODE_EN bit to enable the MODE2 ~ 0 bit configuration. Then set the MODE2 ~ 0 value
and reset the PHY controlling the PHY_RSTn bit. After the reset the 64pin package chip will
be successfully initialized and operate properly.
When the user uses the 64pin package chip,
the code below must be executed in chip initialize routine.
For more detailed information about the PHYCONF SFR, please refer to the section 2.5.10
‘New & Extended SFR’.
