Asynchronous Interface Events

Asynchronous Events are those iPort/AFM interface activities initiated by the

iPort/AFM I

C Host Adapter in response to activities on the I

C Bus.

Slave Transmit Request

This event is caused by the reception of an I

C Bus Slave Transmit message

directed at the current iPort/AFM’s own Slave address.

Prompt: /STR[CR] ‘Slave Transmit Request

Command: /Stext[CR] ‘Slave Transmit Text

The normal Host computer response is to send a Slave Transmit (/Stext[CR])

command.

Note: Upon receiving a Slave Transmit request from a Master Receiver device on

the I

C Bus, iPort/AFM outputs a Slave Transmit Request to its Host device, and

initiates an I

C 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 I

C Bus.

Slave Receive Complete

This event is caused by the reception of an I

C Bus Slave Receive message directed

at the current iPort/AFM’s own Slave address.

The received text is a representation of the data bytes within the Slave Receive

message. The format of this data is controlled by the current setting of the Hex Only

Display Control .

Prompt: /SRCtext[CR] ‘Slave Receive Complete

Command: None Required

General Call Receive Complete

This event is caused by the reception of an I

C Bus Slave Receive message directed

at the I

C General Call Address (00), when iPort/AFM’s General Call recognition is

enabled.
