Hello,
where can I configure Cmod, if it is used by EZI2C (CSD[0].shield_pad)?
I am not sure if I can change EZI2C Interface to SCB[1], because on the Evalkit(4045) it looks for me that the EZI2C is only working with SCB[0]:
thank you
EDIT: If I do auto-assign, it assign Cmod to P4[3] = CSD[0].csh
what's the difference CSD[0].csh to CSD[0].shield_pad ?
Solved! Go to Solution.

Hi,
EzI2C can be configured in SCB blocks 0 and 1. Just ensure that USB-I2C bridge is available to communicate with PC (Assuming you use tuner GUI)
in Eval kit, I assume you are using Kit-prog as USB-I2C bridge. This may be the reason you are using SCB0 block for EzI2C.
Regarding Cmod connections for various PSoC devices, refer to page 113 of http://www.cypress.com/file/46081/download
Thanks,

I've found follow in the document, regarding CMOD:
but the difference P4[3] CSD[0].csh to P4[1] CSD[0].shield_pad is not explained?

Hi Pierre,
There is no difference between the three pins (P4[1], P4[2], P4[3]).
Cmod can be connected to any one of the 3 pins.
Thanks,

Hi Pierre,
The naming is with respect to the pads in CapSense IP.
I think that there is no worry regarding the names. You could very well use either of the three pins to connect Cmod.
Thanks,
