Introduction
MC68HC05X4 Rev 1.0
NOTE:
Address:
The same options as for the MC68HC05X4 are available on the
MC68HC705X4 device. These options must be programmed into the
mask option register (MOR), at EPROM address $1F00, via the
bootloader mode prior to operating the device in single chip mode. The
MOR is latched in at reset in single chip mode to allow emulation of the
masked ROM part. It is recommended that all unused bits in this register
are written as ‘0’.
This register may be written to only in bootloader mode.
The divide-by-10 option is forced during t
MC68HC705X4).
