|
|
|
description:
|
|
NETC V4 Timer provides current time with nanosecond resolution, precise
|
|
periodic pulse, pulse on timeout (alarm), and time capture on external
|
|
pulse support. And it supports time synchronization as required for
|
|
IEEE 1588 and IEEE 802.1AS-2020.

description:
|
|
The reference clock of NETC Timer, can be selected between 3 different
|
|
clock sources using an integrated hardware mux TMR_CTRL[CK_SEL].
|
|
The "ccm" means the reference clock comes from CCM of SoC.
|
|
The "ext" means the reference clock comes from external IO pins.
|
|
If not present, indicates that the system clock of NETC IP is selected
|
|
as the reference clock.
