56F8346 Technical Data
Preliminary
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.
External Reset (EXTR)—Bit 3
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.
Power-On Reset (POR)—Bit 2
6.5.2.6
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
Reserved—Bits 1–0
6.5.3
SIM Software Control Registers (SIM_SCR0, SIM_SCR1,
SIM_SCR2, and SIM_SCR3)
Only SIM_SCR0 is shown below. 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).
Software Control Data 1 (FIELD)—Bits 15–0
6.5.4
This read-only register displays the most significant half of the JTAG ID for the chip. This register
reads $01F4.
