1. Limit (0 - 15 bits) defines a `length_of_segment - 1`. It depends on `G` bit.
* if `G` (55-bit) is 0 and segment limit is 0 - size of segment - 1 byte
* if `G` is 1 and segment limit is 0 - size of segment 4096 bytes
* if `G` is 0 and segment limit is 0xfffff - size of segment 1 megabyte
* if `G` is 1 and segment limit is 0xfffff - size of segment 4 gigabytes
* if `G` (55-bit) is 0 and segment limit is 0, size of segment is 1 byte
* if `G` is 1 and segment limit is 0, size of segment is 4096 bytes
* if `G` is 0 and segment limit is 0xfffff, size of segment is 1 megabyte
* if `G` is 1 and segment limit is 0xfffff, size of segment is 4 gigabytes
2. Base (0-15, 32-39 and 56-63 bits) defines the physical address of the segment's start address.
