UCD3138A的datasheet中,24-bit PWM Timer和16-bit PWM Timer的时钟都是Interface Clock,但是这个Interface Clock时钟频率到底是多少啊?Datasheet中好像找不到!

应该是通过程序寄存器中获得。建议你通过找授权代理商拿到历程来确认,这个应该是要签保密协议才能获得的。
你好,
在文档 UCD3138 Technical Reference Manual中第379页,11.2中有以下描述
The core of the T24 timer is a 24 bit free-running counter. The clock input for the T24 timer can come from a clock within the UCD3138, ICLK, which is nominally 15.6 MHz.
