be supplied by the Phillips part or from the external 5 volt power source through a MIC2536 power switch.
For details on the operation of this USB interface, refer to the i.MX27 data sheet. Figure 2-6 shows the
USB HOST interface connection.
2.3.8
The ADS provides a USB HOST interface that uses a Phillips ISP1105W USB transceiver connected to a
type A USB connector, J8. The interface can function only as a USB host. The interface provides power
on the USB bus. This power is supplied by from the external 5 volt power source through a MIC2536
power switch. For details on the operation of this USB interface, refer to the i.MX27 data sheet. Figure 2-7
shows the USB interface connection.
2.3.9
The ADS has two RS-232 compatible UART Interfaces that service the internal UARTs of the i.MX27.
UARTA is DCE and UARTB is DTE. Both UARTs have full modem signals support. These two inter-
faces connect to UART1 and UART3 signals from i.MX27.
There is also a FIR (Fast Infra Red) transceiver connected to UART3 of the i.MX27 which shares with
the UARTB. The UART Transceivers can be enabled on power up based on S16 DIP switch settings.
Mux and enable controls of IrDA can be software controlled through the CPLD.
