Return |
Slave_Init
|
|
Slave_Init |
| Initialise the Slave with the given Address, or range of Addresses. Only address bits that have a corresponding bit set in the Mask will be compared with the incoming bus address. | |
| - BYTE
|
Address |
| 7 Bit Address of this device (Bit 0 is ignored) | |

Last |
| Sends Ack if 0, else Nak | |
| - BYTE
|
Return |
Slave_Status
|
|
Slave_Status |
| Returns the Slave Status. Bit 0 = 1 Indicates address/data byte available in the buffer to read Bit 5 = 1 Indicates that the last byte received or transmitted was data (else address) | |
| - BYTE
|
Return |
Slave_TxByte
|
|
Slave_TxByte |
| Send a data byte, returns Ack/Nak from Master 0=Ack=More, 1=Nak=Last | |
| - BYTE

Properties |
|
Channel |
| Channel selection | |
|
SDA |
| Pin used for SDA (data signal) | |
|
|
SCL |
| Pin used for SCL (clock signal) | |
|
|
Baud Select |
| Baud rate option selector | |
|
Baud Rate |
| Baud rate to be used | |
|
|
Slew Rate Control |
| Slew Rate Control Enabled or Disabled | |
|
|
SMBus Inputs |
| When Enabled input logic thresholds are compliant with SMBus specification | |
|
Stop Delay |
| On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications. | |
