3.2.5.5 MAC Interface
The OMAP processor connects to the TCP/IP PHY chip via the MAC interface. This interface
adopts the simplified RMII configuration and is mainly used for data service transfer,
tuning&testing, remote upgrade& monitor.
3.2.5.6 USB Interface
This interface is reserved.
3.2.5.7 Control Head Interface
OMAP-L138 controls and communicates with the MCU for the control head via an UART
interface, and the latter controls keypad, LED indicator, and LCD display.
3.2.5.8 GPIO Interface
OMAP-L138 controls electronic switches in baseband and RF sections via some GPIOs.
3.2.5.9 JTAG Interface
OMAP-L138 provides a 14-pin JTAG interface that will be accessed by JTAG emulator for
debugging and downloading programs to NOR flash memory.
3.2.5.10 Rear Board Interface
Signals output from the repeater such as power supply, audio signal, external communication
signals (USB, UART, and PHY), and programmable IO feed to appropriate external interfaces
via the rear board for control and more other functions.
