The host can issue a reset command to the IPAC which has the same functionality as a
hardware reset. In register C9h bit POTA2:SRES (Software Reset) is used to release the
reset which has only effect on the internal functional blocks of the IPAC. The reset pin
RES (pin 34) is not activated.
The duration of the reset is controlled by the host, i.e. SRES is set to ’1’ by the host and
the reset state is active until SRES is set to ’0’. The host must ensure the required reset
timing of the IPAC which is 4 ms.
