4:0IO_IMPEDANCE_CTRLTRIM, RWImpedance Control for MAC I/Os:
Output impedance approximate range from 35-70Ω in 32 steps. Lowest being 11111 and highest being 00000. Range and Step size will vary with process.
Default is set to 50Ω by trim. But the default register value can vary by process. Non default values of MAC I/O impedance can be used based on trace impedance. Mismatch between device and trace impedance can cause voltage overshoot and undershoot.
