#126661 - It's an Analog Devices ADuC845. Responding to: ???'s previous message |
And, after reading the appropriate bible chapter and the chips documentation, I conclude that it should be possible to read the pin even while the pin is being used by the UART.
Using an interrupt would be nice, but the start bit detection would take place in a firmware upgrade part of the program, and there's no guarantee that a valid interrupt vector table is present. |
