Good afternoon
I have the question about PSoc 63 microcontroller, specifically about the "Table 8. Multiple Alternate Functions". ACT #7 from https://www.infineon.com/dgdl/Infineon-PSoC_6_MCU_PSoC_63_with_BLE_Datasheet_Programmable_System-on-.... My particular quesion comes for the notation IPName[x].signal_name[u]:y.  About the scl and sda signals, the "y" in nomenclature is not very clear for me according to the note 2 in the part  "For example, the name tcpwm[0].line_compl[3]:4 indicates that this is instance 0 of a tcpwm block, the signal is line_compl # 3 (complement of the line output) and this is the fourth occurrence (copy) of the signal. Signal copies are provided to allow flexibility in routing and to maximise utilisation of on-chip resources." Can I acces to the same sda and scl signals from pin 6.4 and 6.5 directly from pin 9.0 and 9.1? Are they going to be the same signals as they are copies?

Hi @rod18069

P6.4 and P6.5 use SCB 6 whereas P9.0 and P9.1 use SCB 2 and thus you cannot use the same SCB using these 2 sets of pins. However, if you check P7.0, P7.1, and P8.0, P8.1, both use SCB 4. In this case, you can assign either P7 or P8 for SCB 4 -
