IGF Filter

[shitalshitole]

Hi all,

           I am working on mcu MPC5777c in which I have to generate eTPU Channel interrupt on eTPUA16 . But As per given in MPC5777c reference manual Table 39-3 (IGF_1 Channel Mapping )there is given filter channel number for eTPUA0 - eTPUA14 .So which filter channel should we use for further  eTPUA15 - eTPUA30 channel ?Also, Is it recommended to use IGF filter channel for all etpu channel? 

Thanks ,

Hi, IGF filter is only used with mentioned channels ETPUA0-14, ETPUB0-14 and ETPUC0-14 (considering eTPU chnls only) and in this case it is all least necessary to enable the IGF channels by FGEN bit.
Other channels do not have implemented input glith filters thus it is not needed to configure it.
