* The 16K byte flash in program space page 6 can also be accessed at
a fixed location from $4000 to $7FFF. The 16K byte flash in program
space page 7 can also be accessed at a fixed location from $C000 to
$FFFF.
There are four 32K Flash arrays for MC68HC912DT128A and each
requires a 4-byte register block. A register space window is used to
access one of the four 4-byte blocks and the PPAGE register to map
each one into the window. The register space window is located from
$00F4 to $00F7 after reset. Only two page indices are used to point to
one of the four pages of the register space.
