OFF H

Receivers Active

ON L

Drivers Disabled

ON H

Normal

Selects supply for VL pin. Use setting “VL” for a

separate logic supply, or “VCC” to share a single

supply.

Selects Receiver loopback mode, for use with the

DB9 connector. In this configuration, R1OUT is con-

nected to T1IN and R2OUT is connected to T2IN.

SCH NAME

PURPOSE

For the UART connected to the DB9, this wraps TD

back to RD and RTS back to CTS.
