hi guy
when programing psoc chip like cy8c29466, and power it , there are a period to initialize it , it's about 150 millisecond , right ?
after this time,the generated signals inside psoc started to works .
okay,but at this period (150 ms ) what are the states of my pins ? it's low ,high, high Z , ...?
I need to know the state of it in this time (150 ms ) , i adjust it in PSoC Designer Device Editor , but it's same as i adjusted during this period ?

   

are there an application note explain the state of the pins during this period.
Question 2:Can I control the output of a analog pin  and adjust it to what value for a period of time like i need to adjust a pin to 2.5 volt or 0 volt for a 20 second and then make this pins takes a value of a user models inside the chip ?
( i have a sine signal generated in side psoc on pin p0.1 but i want this output equals 0 for a 20 second, and after this period it's transferred to the sine wave signal output ?

Have a look here for initialization.

   

Controlling an analog output in PSoC1 is difficult. I do not know your project, but I suppose the sine generating can be withheld for 20s.

Hi Abdo Daood

   

On page 100 and 493 in Technical Reference Manual you can find  information relative to pin behaviour during reset.

   

Basically it says that pins are held in Analog Hi-Z during resets except for 2 pins , P1[0] and P1[1]

   

Greetings
