designates the 16-Mbyte area 000FE0H to 000FFFH, 003000H to FFFFFFH as the
CS2 area. Setting B2CS<B2M> to 1 designates the address area specified by the start
address register MSAR2 and the address mask register MAMR2 as CS2 (e.g., if
B2CS<B2M> = 1, CS2 is specified in the same manner as CS0, CS1 and CS3 are).

The following types of wait operation can be specified using these bits. Bit settings
A Reset sets these bits to 000 (2 waits).
