12.2.6.10. Resets Circuitry

The MPFE takes in four primary reset inputs; f2sdram_axi_reset, l3_rst_n, emif_rst_n, and the cs_at_rst_n.

Additional details on MPFE resets are available in the Reset Manager chapter.

The connectivity between the reset manager and the MPFE and MPFE-lite is shown in the following diagram.
