When this pin is pulled "Low" for more than 10µS, the inter- nal registers are set to their default state. See the register description for the default values. NOTE: Internally pulled "High" with a 50K Ω resistor. CS5 CS4 CS3 CS2 CS1 B20 A21 C20 D19 B21 O Chip Select Output The XRT83SH314 can be used to provide the necessary chip selects for up to 5 additional devices by using the 3 MSBs ADDR[10:8] from the 11-Bit address bus. The LIU allows up to 84-channel applications with only using one chip select. See the ADDR[10:0] definition in the pin description. RECEIVER SECTION NAME PIN TYPE DESCRIPTION RxON AB19 I Receive On/Off Input Upon power up, the receivers are powered off. Turning the receivers On or Off can be selected through the microprocessor interface by programming the appropriate channel register if the hardware pin is pulled "High". If the hard- ware pin is pulled "Low", all channels are automatically turned off. NOTE: Internally pulled "Low" with a 50K Ω resistor. RxTSEL Y15 I Receive Termination Control Upon power up, the receivers are in "High" impedance. Switching to internal termination can be selected through the microprocessor interface by program- ming the appropriate channel register. However, to switch control to the hard- ware pin, RxTCNTL must be programmed to "1" in the appropriate global register. Once control has been granted to the hardware pin, it must be pulled "High" to switch to internal termination. NOTE: Internally pulled "Low" with a 50k Ω resistor.
