Note 1: Upon receiving a Slave Transmit request from a Master Receiver device on the I2C Bus, iPort/AFM outputs a Slave Transmit Request to its Host device, and initiates an I2C Clock Stretch (SCL Low) until a Slave Transmit Text command is received from the Host computer. While clock stretching, no other messages can be transmitted on the I2C Bus.

Tilde replaced by "~7E"
