MC68HC908SR12•MC68HC08SR12 — Rev. 5.0
Freescale Semiconductor
The mask option register (MOR) is used for selecting one of the three
clock options for the MCU. The MOR at $FF80 is a read-only register on
the MC68HC08SR12. It is defined by a mask option (hard-wired
connection) specified at the same time as the ROM code submission.
On the MC68HC908SR12, the MOR is a byte located in FLASH
memory, and is written by a FLASH programming routine.
The two registers at $FE08 and $FF09 are reserved locations on the
MC68HC08SR12.
On the MC68HC908SR12, these two locations are the FLASH control
register and the FLASH block protect register respectively.
The monitor program (monitor ROM, $FE10–$FF7F) on the
MC68HC08SR12 is for device testing only.
Electrical specifications for the MC68HC908SR12 apply to the
MC68HC08SR12, except for the parameters indicated below.
