Figure 2-3
The following notes apply to
2-18
1. RESET pin can only be used to reset into user mode, you can not enter BDM using RESET pin.
2. RC filter on RESET pin recommended for noisy environments.
BDM can be entered by holding MS low during POR or writing a 1 to BDM_RESET in the
ColdFire XCSR register with MS low after issuing BDM command.
