1992 I2C bus specification of this version has the following correction
• Remove the software program the content of the slave address because to achieve this function is quite complex and is not used
• Remove the low-speed mode This mode is actually a subset of the entire I2C bus specification need not explicitly described in detail
• Fast mode increases the bit rate will increase 4 times reach 400kbit/s Fast-mode devices are backward compatible in that they can
0 ~ 100kbit/s I2C-bus system
• an increase of 10-bit addressing allows 1024 additional slave address
Slope control and input filter • Fast-mode devices improves EMC performance
