Microprocessor Type Select Input
PTS[2:0] are used to select the microprocessor type interface.
000 = Intel 68HC11, 8051, 80C188 (Asynchronous)
001 = Motorola 68K (Asynchronous)
111 = Motorola MPC8260, MPC860 Power PC (Synchronous)

Hardware Reset Input
Active low signal. When this pin is pulled "Low" for more than 10S, 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
resistor.

Chip Select Output
The XRT83L314 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.

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
resistor.

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
resistor.
