Preliminary
6.5.1.3
Software Reset (SW RST)—Bit 4
This bit is always read as 0. Writing 1 to this field will cause the part to reset.
6.5.1.4
Stop Disable (STOP_DISABLE)—Bits 3–2
00 = Stop mode will be entered when the 56800E core executes a STOP instruction
01 = The 56800E STOP instruction will not cause entry into Stop mode; STOP_DISABLE can be
reprogrammed in the future
10 = The 56800E STOP instruction will not cause entry into Stop mode; STOP_DISABLE can then only be
changed by resetting the device
11 = Same operation as 10
6.5.1.5
Wait Disable (WAIT_DISABLE)—Bits 1–0
00 = Wait mode will be entered when the 56800E core executes a WAIT instruction
01 = The 56800E WAIT instruction will not cause entry into Wait mode; WAIT_DISABLE can be
reprogrammed in the future
10 = The 56800E WAIT instruction will not cause entry into Wait mode; WAIT_DISABLE can then only
be changed by resetting the device
11 = Same operation as 10
6.5.2
SIM Reset Status Register (SIM_RSTSTS)
Bits in this register are set upon any system reset and are initialized only by a Power-On Reset (POR). A
reset (other than POR) will only set bits in the register; bits are not cleared. Only software should clear this
register.

6.5.2.1
Reserved—Bits 15–6
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.5.2.2
Software Reset (SWR)—Bit 5
When 1, this bit indicates that the previous reset occurred as a result of a software reset (write to SW RST
bit in the SIM_CONTROL register). This bit will be cleared by any hardware 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.
6.5.2.3
COP Reset (COPR)—Bit 4
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
