The datasheets on the PIC24 seem rather skimpy. I'm looking at DS70166A which is supposed to cover the PIC24H family of chips. There's no table (like on the 18F series) telling you what's on each pin. There's no list of what bits in what peripheral registers do what. There's no detailed list of instructions (the 18F series lists one or two instructions per page and gives you a lot of info as to how an instruction behaves). This is the datasheet that comes up when I select the 24HJ256GP206 . Is more detailed info on the PIC24 series available? I've been wandering around their website for an hour or two. THANKS!
