|  | 41 | General Description: | 
|  | 42 |  | 
|  | 43 | The I2C protocol is used for the temperature sensors and for | 
|  | 44 | the serial EEPROM which hold the configuration. | 
|  | 45 |  | 
|  | 46 | This file covers functions that allow to read write and do | 
|  | 47 | some bulk requests a specified I2C address. | 
|  | 48 |  | 
|  | 49 | The Genesis has 2 I2C buses. One for the EEPROM which holds | 
|  | 50 | the VPD Data and one for temperature and voltage sensor. | 
|  | 51 | The following picture shows the I2C buses, I2C devices and | 
|  | 52 | their control registers. | 
|  | 53 |  | 
|  | 54 | Note: The VPD functions are in skvpd.c |

|  | 92 | The I2C bus may be driven by the B2_I2C_SW or by the B2_I2C_CTRL | 
|  | 93 | and B2_I2C_DATA registers. | 
|  | 94 | For driver software it is recommended to use the I2C control and | 
|  | 95 | data register, because I2C bus timing is done by the ASIC and | 
|  | 96 | an interrupt may be received when the I2C request is completed. |

|  | 101 | LM80 over B2_I2C_SW register	0	400 kHz		SW | 
|  | 102 |  | 
|  | 103 | Note:	The clock generated by the hardware is dependend on the | 
|  | 104 | PCI clock. If the PCI bus clock is 33 MHz, the I2C/VPD | 
|  | 105 | clock is 50 kHz. |
