charset="utf-8" From: Biju Das Document the serial communication interface (RSCI) used on the Renesas RZ/G3L (R9A08G046) SoC. This SoC integrates the same RSCI IP block as the RZ/G3E (R9A09G047), but it has 3 clocks compared to 6 clocks on the RZ/G3E SoC. The RZ/G3L has a single TCLK with internal dividers, whereas the RZ/G3E has explicit clocks for TCLK and its dividers.
