Is that intentional?
Yes. Functionally, the PPDRs are read-only registers that when read, return the current state of the pins and the SETRs are write-only registers that for each pin configured as an output, if the corresponding bit in the write is a 1, the pin is driven high, and if the bit is 0, no effect. -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
