I3C

The Gowin I3C primitive supports an Improved Inter Integrated Circuit (I3C) protocol, which is a two-wire bus that combines features of I2C and SPI. It enables low power consumption and high data rates, reducing the physical ports required by integrated circuits. The port diagram and description indicate support for various pins such as clock enable (CE), reset input (RESET), and clock input (CLK).

This device is not yet supported in Apicula
