Interface Selection  

The 

Route 56 

supports a variety of electrical interfaces. These interfaces may be selected in two ways. The 

determining bit is found at Base+5, bit position D4, and is identified as IFSEL (

I

nter

F

ace 

SEL

ect). Reference 

the 

Control/Status Register Descriptions

, found in the 

Technical Description

 section of this manual for this 

bit description.

 

When IFSEL = 0, then the values read from M3-M0 are determined by the DIP-switch SW2. 

If all the switches on SW2 are off, then all drivers and receivers are in a high impedance state. Only one 
switch should be set to the on position at a time. The following example illustrates SW-2:  

 

 

 

 

 

 

 

 

When IFSEL = 1, then the values read from M3-M0 are determined by values written to base+5 register. If 

this method is utilized, all switches on SW2 should be set in the off position, unless a default value is 
required. This prevents the application of excess voltages on power-up to external receivers. The following 
table shows the valid options.
