eTimer时钟选择

亲爱的论坛成员你好，
这个问题是关于SPC560P40L1控制器的etimer模块。
目前我的eTimer模块使用64M Hz的“IP总线时钟”。我使用预分频值'32'来获得2M Hz到eTimer模块。
我希望时钟频率为20M Hz（或40M Hz或20M Hz的倍数）。
我在技术数据表的框图中看到（请参阅附件）可以选择时钟源：'时钟'或'IP总线时钟'
晶体振荡器频率为40M Hz。我想使用此频率作为我的eTimer模块的输入，但我不知道如何甚至可以将此频率路由到eTimer？
如果有人可以在这方面分享任何有用的提示或建议，我会很高兴。
最好的祝福

Hello Dear Forum members,
This question is regarding SPC560P40L1 controller's eTimer module.
At the moment my eTimer module using 'IP Bus clock' which is of 64M Hz. I am using prescaler value of '32' to get 2M Hz to eTimer module.
I want to have clock frequency of 20M Hz(or 40M Hz or multiples of 20M Hz basically).
I see in the block diagram of technical datasheet that(Please see attachments) there is option to choose from clock sources: 'Clock' or 'IP Bus clock'
The crystal oscillator frequency is 40M Hz. I would like to use this frequency as input to my eTimer module but i don't know how or even it's possible to get this Frequency routed to eTimer ?
I would be happy if someone can share any useful tips or suggestion in this regard.
Best regards
Sathish
