MC68HC705J2
This section describes how to use the MC68HC05J1 emulation mode to
achieve compatibility with MC68HC05J1 devices.
Use the bootloader function to put the MCU in MC68HC05J1 emulation mode.
To activate the emulation mode:
In MC68HC05J1 emulation mode, the MCU operates as an MC68HC05J1 with
the following exceptions:
1. Connect pin PB5 to V
2. Program the J1 bit (in the mask option register) high.
• The emulation mode does not support the RC oscillator mask option of
• The emulation mode does not support the STOP disable mask option of
• The emulation mode has no self-check function.
