2.11 USB
The K60N512 features a USB full-speed/low-speed OTG/Host/Device controller with built-in
transceiver. The TWR-K60N512 routes the USB D+ and D- signals from the K60 MCU to the Primary
Connector, allowing the connection to external USB connectors or additional circuitry on a Tower
peripheral module.
The TWR-SER module included as part of the TWR-K60N512-KIT provides a USB OTG/Host/Device
interface with a mini-AB USB connector. There are many configuration options that can be selected to
evaluate different USB modes of operation. By default, the TWR-SER is configured for USB Device
operation. Please refer to the documentation included with the TWR-SER for more information on the
configuration options.
2.12 Secure Digital Card Slot
A Secure Digital (SD) card slot is available on the TWR-K60N512 connected to the SD Host Controller
(SDHC) signals of the K60 MCU. This slot will accept SD memory cards as well as Secure Digital Input
Output (SDIO) cards. Refer to Table 6 “I/O Connectors and Pin Usage Table” for the SDHC signal
connection details.
2.13 External Bus Interface – FlexBus
The K60 device features a multi-function external bus interface called the FlexBus interface controller
capable of interfacing to slave-only devices. The FlexBus interface is not used directly on the TWR-
K60N512. Instead, a subset of the FlexBus is connected to the Primary Connector so that the external
bus can access devices on Tower peripheral modules. Refer to Table 7 “TWR-K60N512 Primary
Connector Pinout” and sheet 8 of the TWR-K60N512 schematics for more details.
3 Jumper Table
There are several jumpers on the TWR-K60N512 that provide configuration selection and signal
isolation. Refer to the following table for details. The default installed jumper settings are shown in
bold with asterisks.
