6.5.2.3
When 1, the COPR bit indicates the Computer Operating Properly (COP) timer-generated reset has
occurred. This bit will be cleared by a Power-On Reset or by software. Writing a 0 to this bit position will
set the bit, while writing a 1 to the bit will clear it.
6.5.2.4
If 1, the EXTR bit indicates an external system reset has occurred. This bit will be cleared by a Power-On
Reset or by software. Writing a 0 to this bit position will set the bit while writing a 1 to the bit position will
clear it. Basically, when the EXTR bit is 1, the previous system reset was caused by the external RESET
pin being asserted low.
6.5.2.5
When 1, the POR bit indicates a Power-On Reset occurred some time in the past. This bit can be cleared
only by software or by another type of reset. Writing a 0 to this bit will set the bit, while writing a 1 to the
bit position will clear the bit. In summary, if the bit is 1, the previous system reset was due to a Power-On
Reset.
6.5.2.6
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.5.3
Only SIM_SCR0 is shown in this section. SIM_SCR1, SIM_SCR2, and SIM_SCR3 are identical in
functionality.
6.5.3.1
This register is reset only by the Power-On Reset (POR). It has no part-specific functionality and is
intended for use by a software developer to contain data that will be unaffected by the other reset sources
(RESET pin, software reset, and COP reset).
