Dprotocol.rst157 I3C HDR commands
160 HDR commands should be used for anything that is device specific and requires
163 The first thing attached to an HDR command is the HDR mode. There are currently
167 * HDR-DDR: Double Data Rate mode
168 * HDR-TSP: Ternary Symbol Pure. Only usable on busses with no I2C devices
169 * HDR-TSL: Ternary Symbol Legacy. Usable on busses with I2C devices
171 When sending an HDR command, the whole bus has to enter HDR mode, which is done
173 Once the bus has entered a specific HDR mode, the master sends the HDR command.
