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.
