Thank you GoForSmoke and PaulRB for all this great information.I have a follow up question regarding clock speed and supply voltage requirements… I'm trying to control the skipping-type behavior of this chip in a Sony Discman (while a CD is playing), which runs at 4.5v. I understand the chip's system clock is 16mzh but do my communication signals have to be at the system clock speed? Thanks again
No, they have to be at the correct serial baud rate.
I'd be looking to the disc and if the Sony is old then the laser as problem sources long before "the chip".
