Part Number:MSPM0G3507
今天使用syscfg配置PWM,版本是1.21.1,,,因为需要使用到捕获比较寄存器的影子寄存器,居然发出错误警告:Shadow Capture Compare mode is only supported on on Timer A instances and Timer G6-G7 instances. Please select a Timer instance from PinMux if available.
实在搞不懂,尝试了使用不同的计数器型号,都是会发出错误警告
Channel Update Mode 就是这这个参数里设置,当定时器到达0或者重载时候,我选择的是:Capture Compare value has effect one TIMCLK cycle after timer counter reaches Capture Compare value in up counting mode
就发出错误警告,
如果选择这个 Capture Compare value has immediate effect
就不会出现错误
查看了规格书和参考手册,某些定时器是具有CC影子寄存器的,在是配置上就是出现错误

您好,
下面帖子也遇到了类似问题。

请直接测试一下这个程序timx_timer_mode_pwm_edge_sleep_shadow
