| 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. |
