6.5.1.2
6.5.1.3
Writing 1 to this field will cause the part to reset.
6.5.1.4
6.5.1.5
6.5.2
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
This bit field is reserved or not implemented. It is read as zero and cannot be modified by writing.
6.5.2.2
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.

RESET
0 = OnCE clock to 56800E core enabled when core TAP is enabled
1 = OnCE clock to 56800E core is always enabled
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
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
