TMS570LS3137 QFP144 GIOA and GIOB mux information incomplete

Other Parts Discussed in Thread: TMS570LS3137

Dear community,

In the datasheet for TMS570LS3137 is not indicated where the GIOA and GIOB pins are multiplexed. They are all 16 pins indicated for BGA package but not for QFP144. Specifically they are indicated GIOA[2], [5], [6], [7] and GIOB[2] but they should be 16 GIO pins multiplexed with another functions.

Please share to me such information or indicate where I can find it.

Thank you in advanced.

    Zeus,

    Those GIO pins are not available in 144 pin package. You may need to consider using the GIO functionality of other peripheral modules if you need more GIO function. Most peripheral module pins also supports GIO function. The only limitation is that they do not support input capture interrupts.

    Thanks and regards,
