Device Guide XMC4000 Triple-Hall Output Pattern for BLDC Motor Commutation Control A slice may have its output pin modulated by external events. This function (and the active level of the event source) should be mapped to one of the 3 inputs of the slice in the CC4/8yCMC and CC4/8yINS registers. Modulation alternatives should be mapped in CC4/8yTC - for Status Bit Clear or just Output Gating on events. -

Device Guide XMC4000 Getting Started with POSIF in Triple-Hall Mode 5.6.8 Multi-Channel Synchronization to Shadow Transfers When it is necessary to perform certain compound shadow transfers synchronously with the update of the Multi- Channel pattern, then the CCU4xMCSS trigger can synchronize those scenarios. The synchronization will be performed via the GCTRL.MSEy bit field respective the shadow transfers configured on the GCTRL.MSDE field. -
