Struct InternalRefClock 

Source 
pub struct InternalRefClock<POut, PIn> { /* private fields */ }
Expand description

RMII reference clock derived from the ESP32-P4 MPLL at 50 MHz.

The MPLL output is driven out on a REF_50M_CLK output pad (GPIO23 or GPIO39) and must be looped back externally into one of the EMAC_RMII_CLK input pads (GPIO32, GPIO44, or GPIO50).

Implementations§

Source§

impl<POut, PIn> InternalRefClock<POut, PIn>

Source

pub fn new(ref_clk_out: POut, ref_clk_in: PIn) -> Self

Creates an internal MPLL clock configuration.

  • ref_clk_out — the pad that will output the 50 MHz REF_50M_CLK signal (GPIO23 or GPIO39).
  • ref_clk_in — the pad that receives the looped-back signal (GPIO32, GPIO44, or GPIO50).
