I will use S12XDP512 with normal expanded mode (attached external RAM but program memory is internal flash). I want to know that am I right:
I can do mode selection in two ways, first during reset pin active (low) by hardware pull up BKGD- MODC, pull down PE6-MODB pull up PE5-MODA and pull up PK7-ROMCTL. Second way is setup this bits by software in MODE register.
So if I do this settings from software by MODE register I can use this pins (except BKGD) for general purpose I/O.
