Reset Generation Module (MC_RGM)MPC5606S Microcontroller Reference Manual, Rev. 71080 Freescale Semiconductor31.3.1.3 Functional Event Reset Disable Register (RGM_FERD)This register provides dedicated bits to disable functional reset sources.When a functional reset source isdisabled, the associated functional event will trigger either a Safe mode request or an interrupt request (seeSection 31.3.1.5, Functional Event Alternate Request Register (RGM_FEAR)). It can be accessed inread/write in either supervisor mode or test mode. It can be accessed in read only in user mode. Each bytecan be written only once after power-on reset.Address 0xC3FE_4004 Access: Supervisor read/write0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15RD_EXRD_FLASHD_LVD45D_CMU0_FHLD_CMU0_OLRD_FMPLL0D_CHKSTOPD_SOFTD_CORED_JTAGWPOR 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0Figure 31-4.
