Freescale Semiconductor

Preliminary

6.5.1.2

OnCE Enable (ONCE EBL)—Bit 5

•

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

•

1 = OnCE clock to 56800E core is always enabled

6.5.1.3

Software Reset (SW RST)—Bit 4

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

6.5.2.1

Reserved—Bits 15–6

This bit field is reserved or not implemented. It is read as zero 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.
