--------------redirected here from touch screen section -----------------------------------------
Hello,
is it possible to get detailed description of the TSC2301? I mean a similar to the picture on the page 2 of SLAS371D but with a deeper level by at least two.
Why I am asking. From this picture I should get the output from OSC on pin GPIO_5. I have started the internal OSC, OSCC=1, BCKC=1, GPIO CONTROL REGISTER=0x3f3f. However the GPIO_5 is still low, no SCS output. Probably it cannot be driven from the internal OSC which is not clear from the diagram.
Also the datasheet is very inconsistent. E.g. "This register also contains a bit, SDAVB which mirrors the state of the DAVB output line.". Neither SDAVB nor DAVB are defined at all. Next, the PENIRQ should be low during "Touch Screen Scan X, Y and Z PENIRQ Initiated" - it behaves exactly as on TSC21xx. Down/up during earch coordinate.
Best
