I would suggest you post a tech case at www.cypress.com, main menu on
homepage, "Support", "Technical Support", "Create a Case"
I looked at part using Designer 5.3, I could not find any obvious route. But
my experience in Power PSOC severly limited.
Unfortunately, HYSTCTL0 can take the feedback input only from CSA0 or FN0_0. It is not possible to route FN0_1 to HYSTCTL0 feedback input.
Thanks for the help! I guess ill have to physically rout it to FN_0_0 untill i have a new board built.
