Page 12: I 2 C-Bus
IPC@CHIP - SC12 Hardware Manual v1.1 [05.11.2002] C-Bus The IPC@CHIP family microcontroller handles up to 127 external slaves. It is always master. Slave mode is not implemented. I²C is implemented by software emulation. Maximum Frequency is about 30 kHz without longer breaks by interrupt. - Page 13 IPC@CHIP - SC12 Hardware Manual v1.1 [05.11.2002] Pin Name Type Function The NMI is for detecting low supply power and the following data backup only. A reset has to follow after the NMI. At turn-on the IPC@Chip I/O pins are configured as follows:...
