|
* Flags value format:
|
||
|
|
* - 0x001F: 0000 0000 0001 1111 -> the shift value to read or write the flag's bit
|
||
|
|
* - 0xFFE0: 1111 1111 1110 0000 -> index of the value in the array
|
||
|
|
*
|
||
|
|
* `FLAG` is a macro that allows you to get the final value from the index and the slot number.
