38 / 124 page  Pin Description III-24 Slave Controller – ET1100 Hardware Description 3.6.3.1 Configurations with 2 ports For configurations with 2 ports, logical ports 0 and 1 are used. The port signals are available at physical ports 0 and 1, depending on the port configuration. P_MODE[1:0] has to be set to 00. P_CONF[1:0] determine the physical layer of logical ports (1:0). P_CONF[3:2] are not used, nevertheless, P_ CONF[2] should not be left open (connection to GND recommended). P_CONF[3] should be pulled down if possible (denoted with ‘-‘ in the table), if your application allows this.

The port signals are available at physical ports 0, 1 and 2, depending on the port configuration. P_CONF[2:0] determine the physical layer of logical ports 2, 1, 0, or logical ports 3, 1, 0, depending on the P_MODE settings (P_CONF[2] is either used for logical port 2 or logical po rt 3). P_CONF[3] should be pulled down if possible (denoted with ‘-‘ in the tables), if your application allows this.
