10.7.5.10 KEU IV_1 Register (KEUIV1)
The KEU IV_1 register is a general purpose IV register, shown in
initialization phase of the f8 algorithms for 3GPP, GSM A5/3, EDGE A5/3, GPRS GEA3, and f9 algorithm
for 3GPP. The appropriate value as defined by the standards for each algorithm must be written before a
new message is started.
After the initialization phase has been completed, the KEU IV_1 register is no longer used for the
remainder of f8 processing. However, if 3GPP f9 is selected because the KEU IV_1 register contains the
direction bit as defined by the 3GPP standard, the KEU IV_1 register must be written back during context
switches to complete the generation of the 3GPP MAC.
Table 10-58
The following figure shows how the KEU IV_1 register can be differentiated for different applications.
