Example
Read
IOBOOT * Returns value for all general-purpose I/O
Ex. Return a value of 54, or binary …. 0011 0110, indicates IO 2, 3, 5, and 6 will turn on at power-up if configured as outputs. All other outputs are off.
Write
IOBOOT=147161088 * 147161088 in binary is 0000 1000 1100 0101 1000 0000 0000 0000, IO 16, 17, 19, 23, 24 and 28 turn on at power up if configured as outputs. all other outputs are off.
Notes
- Only the General-purpose ports set as Outputs by the IOCFG command are effected by the IOBOOT command.
- Input values are NOT changed due to this command.
- To write the value to the device’s flash memory, use the STORE command.
