Note: An I3C Master that supports version 1.1 or greater of the full I3C Specification might emit the SETBUSCON CCC with Bit[4] set to 1’b0. In that case, an I3C Slave that supports version 1.1 or greater of the I3C Basic Specification should ignore Bit[4]. An I3C Master that supports any version of the I3C Basic Specification shall not emit the SETBUSCON CCC with Bit[4] set to 1’b0; for an I3C Basic Master, 1’b1 is the only valid value for Bit[4]. |
