Usage Table” for the specific K60 pin connections to the Touch TWRPI socket.
2.10 Ethernet
The K60D100M features a 10/100 Mbps Ethernet MAC with MII and RMII interfaces. The TWR‐
K60D100M routes the RMII interface signals from the K60 MCU to the Primary Connector, allowing the
connection to an external Ethernet PHY device on a Tower peripheral module.
When the K60 Ethernet MAC is operating in RMII mode, synchronization of the MCU clock and the 50
MHz RMII transfer clock is important. The MCU input clock must be kept in phase with the 50 MHz
clock supplied to the external PHY. Therefore, the TWR‐K60D100M provides the option (see
description for J10 in Table 5) to clock the MCU from an external clock from the CLKIN0 pin on the
Primary Connector. The Tower peripheral module implementing the RMII PHY device should drive a 50
MHz clock on the CLKIN0 pin that is kept in phase with the clock supplied to the RMII PHY.
The TWR‐SER module that comes as part of the TWR‐K60D100M‐KIT provides a 10/100 Ethernet PHY
that can operate in either MII or RMII mode. By default the PHY is boot strapped to operate in MII
mode; therefore jumper configuration changes may be required. In addition to that, the TWR‐
K60D100M also allows the option to route CLKIN0 from the TWR‐SER 50 MHz to the
ENET_1588_CLKIN. Table 4 shows the settings for proper interoperability between the Ethernet
interface on the TWR‐SER and the TWR‐K60D100M.
