the RTL8211B. Figure 8 shows the connection between the MPC837xE eTSEC1 and eTSEC2 to the
RTL8211B.

2.1.11 RS-232 Port
Figure 9 illustrates the serial port connection using a SP3232 3.3 V RS-232 driver to interface with a 2 x
5 Header. This serial connection runs at up to 115.2 Kbps.

2.1.12 USB 2.0 Interface
The MPC837xE has a internal USB modules (dual-role (DR) module). On the MPC837xE-RDS board, it
connects to the USB PHY (USB3300) through the 8-bit UTMI low-pin-count interface (ULPI). The
