你好!
没看出有什么问题, P78是把hardware mode 和software mode的引脚集合在一起。
datasheet的P2和P5是分开标注的引脚。
我查询了一下,以前有客户问过类似的问题。
是有些差异,我在去问下这个芯片的设计工程师,看看是不是P5的引脚定义有误。
下面是工程师的回复。
Actually, the three pins are GPIO, and the function could be defined by register 0x61(GPIO1/ pin11 ), 0x62(GPIO2/ pin12 ), 0x63(GPIO0/ pin10 ).
and of course, you can also use PPC3 to config it like below which is the default setting of 48k stereo mode:
