A Page in the 65x architecture is 256 contiguous bytes.

A page boundary occurs between byte $FF of one page and byte $00 of the next. In emulation mode, crossing a page boundary incurs a one cycle penalty.

The zeropage is located at $00:0000.

Most pages begin at an address of the form $xx:yy00, where xx is the bank number and yy is the page number, but the direct page can begin anywhere in bank zero.

CGRAM and lowoam are exactly two pages.
