**Set and Clear Bit Port Parallel**

set and clear bit parallel port |

**can be conducted by operating logic OR into input data by logic grade 1**

*Set Bit*For example:

Data= 11111110 is operated by logic OR toward data 11111110, so it will be 11111110 OR 11111111 the result 1111 1111

The result is set bit toward the last data.

**can be conducted by operating logic AND toward input data by logic grade 0**

*Clear Data*For example:

Data: 11111111 is operated by logic AND toward data 1111 1110, so it will be 11111111 or 11111110 the result 11111110

The result is clear bit toward the last data

On the above explanation, each data is displayed in form of binary (0 and 1), in accessing parallel port, the data is sent in format hexadecimal or decimal. Therefore, the data then must be converted first into hexadecimal format or decimal one if any conversion way from binary data to decimal one is not understood yet.
