The maximum number of pairs = ( ↓ Number of bitmap areas ⎟ required number of bitmap areas ↓ )

The ↓…↓ symbols enclosing a value indicate that the value should be rounded down to the nearest integer.

Note: If the calculated maximum number of pairs exceeds 32,768, the actual maximum number of pairs is limited to 32,768.

Table 3-8 illustrates the maximum number of pairs according to each emulation type, when pairs are created without use of VLL volume.
