I'm having problems with SPI0 pin reassignment at MC9S08PA32.
I am unable to change SYS_SOPT1 register. Why I can't change this register?
My assembly code is:
STA SYS_SOPT1 ;Directs the SPI0 port for PORTE
Afer I write this register, the value of this register doesn't change.
Does anybody know what is the problem? Is there a password to change this register like there is for to change the watchdogs registers?
