PWM通道对应哪些子模块？

我试图最大化我可以在SPC560P40L1CEFAR（64引脚）上同时使用的独特16位PWM输出的数量。我从规范中收集了以下信息，其中一些似乎是冲突的。


1个Flex PWM单元
8个互补或独立的渠道
4个PWM子模块
PWMX引脚可以选择从每个子模块输出第三个PWM信号
我计算10个PWM输出通道：
A0，A1 A2，B0，B1，B2，B3，X0，X1，X2;
B2和X2都只能在引脚52上使用

哪些输出通道对应哪些子模块？哪些通道不能产生独特的PWM信号？

我还注意到SPC560P（34L和40L）规格第24页的一个悖论。它在同一页面上说：
不用于PWM生成的通道可用于输入捕获功能。
然后几行说：
不支持PWMA，PWMB和PWMX通道的捕获功能

这是否意味着我需要使用定时器引脚来代替PWM引脚进行输入捕捉？

I am trying to maximize the number of unique 16-bit PWM outputs that I can use simultaneously on the SPC560P40L1CEFAR (64 pins).  I have gathered the following information from the specification, and some of it appears to be conflicting.


1 Flex PWM unit
8 complementary or independent channels
4 PWM submodules
PWMX pin can optionally output a third PWM signal from each submodule
I count 10 PWM output channels though:
    A0, A1 A2, B0, B1, B2, B3, X0, X1, X2;
    B2 and X2 are both only available on pin 52

Which output channels correspond to which submodules?  And which channels cannot produce unique PWM signals?

I also noticed a paradox on page 24 of the SPC560P (34L and 40L) specification.  On the same page it says:
    Channels not used for PWM generation can be used for input capture functions.
A few lines down it then says:
    Capture capability for PWMA, PWMB, and PWMX channels not supported

Does this mean I need to use timer pins for input capture instead of the PWM pins?
