| TWSI protocol implementation. |
| |
| General Description: |
| |
| The TWSI 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 TWSI address. |
| |
| The Genesis has 2 TWSI buses. One for the EEPROM which holds |
| the VPD Data and one for temperature and voltage sensor. |
| The following picture shows the TWSI buses, TWSI devices and |
| their control registers. |
| |
| Note: The VPD functions are in skvpd.c |

| . |
| The TWSI 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 TWSI control and |
| data register, because TWSI bus timing is done by the ASIC and |
| an interrupt may be received when the TWSI request is completed. |
| |
| Clock Rate Timing: MIN MAX generated by |
| VPD EEPROM: 50 kHz 100 kHz HW |
| LM80 over TWSI 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. |
