Function Description
The L9_SBIT set bit procedure lets you set to 1 (ON) a specified bit within a word located in %MW memory.
IN_REG is the word that contains the bit to be set to 1. The BITLOC value identifies the specific bit - 1 through 16 - to be set to 1.
When the ENABLE pin is turned ON, the state of the controlled bit is set to 1; when the ENABLE pin is turned OFF, the controlled bit remains set to 1. The OUT output echoes the state of the ENABLE pin.
