Register (FLCR). Details for these operations appear later in this
section.
The FLASH is organized internally as a 8192-word by 8-bit CMOS page
erase, byte (8-bit) program Embedded Flash Memory. Each page
consists of 64 bytes. The page erase operation erases all words within
a page. A page is composed of two adjacent rows.
The address ranges for the user memory and vectors are as follows:
• $E000–$FDFF; user memory for the MC68HC908GR8
$EE00–$FDFF; user memory for the MC68HC908GR4.
• $FF7E; FLASH block protect register.
• $FE08; FLASH control register.
• $FFDC–$FFFF; these locations are reserved for user-defined
interrupt and reset vectors.
NOTE:
Programming tools are available from Motorola. Contact your local
Motorola representative for more information.
A security feature prevents viewing of the FLASH contents.⁽¹⁾
