NXP/ST Power Architecture: Cannot access SFRs on a Bolero device

10-May-2024

When trying to access SFRs on a MPC56/SPC56 Bolero device with 512 KB internal FLASH memory problems occur. 


Possible solution

Write 0x80808000 to the CGM_SC_DC0 register (address 0xC3FE037C) before accessing any SFR and check if clock(s) for peripheral modules are switched on. This switches on clocks for all peripheral modules.
