5.6 Mask Option Register (MOR)
MC68HC908JL8
MOTOROLA
NOTE:
—
Rev. 2.0
Non-volatile FLASH register; write by programming.
Configuration and Mask Option Registers (CONFIG & MOR)
Address:
The mask option register (MOR) is implemented as a byte within the
FLASH memory, and therefore can only be written during a
programming sequence of the FLASH memory. This register is read
after a power-on reset to determine the type of oscillator selected.
(See
OSCSEL — Oscillator Select Bit
Bits 6–0 — Should be left as logic 1’s.
When Crystal oscillator is selected, the OSC2/RCCLK/PTA6/KBI6 pin is
used as OSC2; other functions such as PTA6/KBI6 will not be available.
Erased:
Reset:
Read:
Write:
OSCSEL selects the oscillator type for the MCU. The erased or
unprogrammed state of this bit is logic 1, selecting the crystal
oscillator option. This bit is unaffected by reset.
