7.0 ERROR INSERT REGISTER
The Error Insertion Register (EIR) controls circuitry within the DS2172 that allows the generated pattern
to be intentionally corrupted. Bit errors can be inserted automatically at regular intervals by properly
programming the EIR0 to EIR2 bits or bit errors can be inserted at random (under microcontroller
control) via the EIR.3 bit.

-EIR.7
Not Assigned. Should be set to 0 when written to.
-EIR.6
Not Assigned. Should be set to 0 when written to.
TINV
EIR.5
Transmit Data Inversion Select.
0 = do not invert data to be transmitted at TDATA
1 = invert data to be transmitted at TDATA
RINV
EIR.4
Receive Data Inversion Select.
0 = do not invert data received at RDATA
1 = invert data received at RDATA
SBE
EIR.3
Single Bit Error Insert. A low to high transition will create a single bit
error. Must be cleared and set again for a subsequent bit error to be
inserted. Can be used to accomplish rates not addressed in Table 3 (e.g.,
BER of less than 10
-7).
EIB2
EIR.2
Error Insert Bit 2. See Table 3.
EIB1
EIR.1
Error Insert Bit 1. See Table 3.
EIB0
EIR.0
Error Insert Bit 0. See Table 3.
