B.4 Reserved Registers
The two registers at $FE08 and $FE09 are reserved locations on the MC68H(R)C08JL3E/JK3E.
On the MC68H(R)C908JL3E/JK3E, these two locations are the Flash control register and the Flash block
protect register respectively.
B.5 Mask Option Registers
This section describes the mask option registers (MOR1 and MOR2). The mask option registers enable
or disable the following options:
B.5.1 Functional Description
The mask options are hard-wired connections, specified at the same time as the ROM code, which allow
the user to customize the MCU.
B.5.2 Mask Option Register 1 (MOR1)
COPRS — COP reset period selection bit
LVID — Low Voltage Inhibit Disable Bit
