In a T-series processor,


1. Do Reset Control Word Status Registers(DCFG_CCSR_RCWSRn) reflect only RCW recieved from NOR flash or RCW received from any other source (including Hard coded RCW at POR)


2. Do GPIO programming require TLBs and MMU configuration?


3. Do GPIOs programming require PLLs to be correctly configured?
