The default value of Hard-strap in REG 18h.1Ch depends on each pins' strap setting when
power-on reset, refer to the section 5.8 Strap Pins Table for more detail.
The Hard-strap's setting can be overridden via Soft-strap (REG 18h.1Ch.[5:0]). The updated setting will
be applied until software reset is asserted (write REG 10h.11h.[0] to 1).
