7. ERROR INSERT REGISTER
The Error Insertion Register (EIR) controls circuitry within the DS21372 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.

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.
