3. Activation of the on-chip PHY module
To activate the on-chip PHY module, set the pin
function registers of Port C as something but EtherC
function, that is, I/O ports and LED outputs of the on-
chip PHY.
• PCCRH2 = H'0000
• PCCRL1 = H'0000
• PCCRL2 = H'FF00
……..
Amended
In the case of utilizing the external PHY LSI, select the
EtherC function of the pin function controllers and then set
up the internal registers of the PHY LSI with the MII
management frame.
1. Activation of the external PHY LSI.
Select the EtherC functions with pin function controller.
• PCCRH2 = H'0155
• PCCRL1 = H'5555
• PCCRL2 = H'5555
