3.3
In order for the MUSAC to operate with a 4096-kHz device clock the CPS bit in the CFR register
needs to be reset. This has to be done before the CM reset and needs 1.8 s. For a flow chart of
this process refer to figure 18.
3.4
With MOD:SB being logical 1 the MUSAC works as a backup device in redundant systems. It can
be accessed via the P interface and works internally like an active device. However, the outputs
are high impedance. If the SB bit is reset, the outputs are switched to low impedance for the
programmed active channels and this MUSAC can take over from another device which has been
recognized as being faulty.
