[3] 预留CBUS地址,使CBUS兼容设备和I2C-bus兼容设备能够在同一系统中混合使用。I2C总线的兼容设备不允许在这个地址接收时响应。 [4] 其中包括为不同总线格式保留的地址,以使I2C和其他协议能够混合使用。只有能和这样格式工作的I2C兼容设备允许对这样的地址响应。 本地系统内的地址分配由系统架构师负责,系统架构师必须...

If that is the case, why not specify the minimum rise/fall time as 20ns instead? In I2C Bus specification Revision 7.0, the minimum rise/fall time is no longer dependent on the bus capacitance. What is the reason? Thank you. Rgds Danz...

One Fast-mode Plus I2C-bus interface with monitor mode and with open-drain I/O pins conforming to the full I2C-bus specification. Supports data rates of up to 1 Mbit/s. One standard I2C-bus interface with monitor mode and standard I/O pins. ...
I2C-bus interface supporting full I2C-bus specification and Fast-mode Plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode (not onLPC1112FDH20/102). Clock generation: 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be...
根據NXP 的《I2C-bus specification and user manual》最簡單的解決辦法就是使用 GPIO 模擬 I2C 的連續 9 位時鐘或者更多時鐘,因為協議規定 I2C 的通常傳輸的數據寬度為 8 位和 1 位應答位,額外的時鐘都會被認為是停止信號,所以不管從機處於何種狀態,這種方法都能使從機釋放 SDA ,進入正常的傳輸狀態。
I2C-bus interface supporting full I2C-bus specification and Fast-mode Plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode. Other peripherals: Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors. ...
Three enhanced I2C-bus interfaces, one with a true open-drain output supporting the full I2C-bus specification and Fast-mode Plus with data rates of 1 Mbit/s, two with standard port pins. Enhancements include multiple address recognition and monitor mode. ...
