+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.
