Where does the ARM processor Wake up when powered on?

Note: This was originally posted on 27th September 2012 at http://forums.arm.com

I have used PIC24F series before . When the microcontroller wakes up or when power is apllied to POR . All I/) ports are set as Inputs etc . Those details given clearly in Datasheet.
I wish to know where does the Arm processor wake up? I read boot rom is mapped to address 0 and it automatically executed and it points to flash memory prior to executing User code . What happens to I/O ports? Does all the I/O ports been set as i/p ?
