Power to the USB ports is provided by a MAX1558H switch, which supplies 5 V at up to

1 A per port. The power enable and power-fault-detect pins are directly connected to the

T1024 processor for individual port management.

The below figure shows how the USB connectivity is implemented on the T1024RDB.

2.15 UART

The T1024 processor has two UART controllers, which provides a RS-232 standard

interconnection between the board and an external host. The serial connection is typically

configured to run at 11.5 Kbit/s.

Each UART supports:

• Full-duplex operation

• Software-programmable baud generators

• Clear-to-send (CTS) and ready-to-send (RTS) modem control functions
