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

|
|
The I2C bus may be driven by the B2_I2C_SW or by the B2_I2C_CTRL
|
|
and B2_I2C_DATA registers.
|
|
For driver software it is recommended to use the I2C control and
|
|
data register, because I2C bus timing is done by the ASIC and
|
|
an interrupt may be received when the I2C request is completed.
|
|
|
|
Clock Rate Timing: MIN MAX generated by
|
|
VPD EEPROM: 50 kHz 100 kHz HW
|
|
LM80 over I2C Ctrl/Data reg. 50 kHz 100 kHz HW
|
|
LM80 over B2_I2C_SW register 0 400 kHz SW
|
|
|
|
Note: The clock generated by the hardware is dependend on the
|
|
PCI clock. If the PCI bus clock is 33 MHz, the I2C/VPD
|
|
clock is 50 kHz.
