3.1 Mode Select
The DS2174 is configured to operate in bit, nibble, or byte mode by using the MODE1/MODE0 bits in
Control Register 2.

3.1.1 Error Insertion
The DS2174 inserts bit errors at a particular rate by setting the error insertion bits in Control Register 2
(Table 3-B). In addition, the device inserts errors on command by setting the SBE bit in Control Register
2. The bit that occurs after the rising edge of the SBE insert bit is inverted. In the case of the QRSS
pattern, this could result in a string of 0’s longer than 14 bits; the DS2174 delays the erred bit by 1 clock
cycle.
Data in the nibble and byte modes is presented 4 or 8 bits at a time. When in nibble or byte mode and
selecting 10-1 error rate, the device actually produces an error rate of 8-1. When in byte mode and
selecting an error rate of 10-2, the device produces an error rate of 8-2.
