Operation with a 4096-kHz Device Clock
In order for the MTSC 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 up to 1.8
s. Please keep
in mind, MOD:RI has to be reset prior to performing an indirect register access. For a flow chart of
this process refer to figure 19.
