VCCD pin issue and TCPWM out

Hello All,

   

I am using CYBL10161-56LQXI in my project. The pin 56 of the chip is designated as in Table 1

   

56 | VCCD | POWER | Regulated 1.8-V supply; connect to 1-μF capacitor

   

So, does this mean this pin need not be connected to 3.3V supply of my board and should be left unconnected with bypass cap as mentioned in the datasheet?

   

Also, There are 2 TCPWM blocks in the chip and I need line_out and line_n_out of both the blocks on output pins but only one TCPWM block is allowed to have pins on MCU port. How can I make PSOC creator use both TCPWM outputting from both line and Line_n outs on the pins?

   

 

   

Thanks

That pin needs to be connected as described here.

@bobgoar, Yes, I see that. But, it does not say that i should or should not connect it to board PSU output of 3.3V. So, should i keep it unconnected or connect it to 3.3V supply line?

The schematic I was looking at says one side of the Cap  goes to gnd the other side of the Cap to this pin  The power supply voltage doesn't matter what ever you selected.

No power supply voltage to this pin just the cap to ground.
