title: NETC Blocks Control

description:
  Usually, NETC has 2 blocks of 64KB registers, integrated endpoint register
  block (IERB) and privileged register block (PRB). IERB is used for pre-boot
  initialization for all NETC devices, such as ENETC, Timer, EMIDO and so on.
  And PRB controls global reset and global error handling for NETC. Moreover,
  for the i.MX platform, there is also a NETCMIX block for link configuration,
  such as MII protocol, PCS protocol, etc.
