Register Descriptions
6.3.3
SIM Software Control Registers (SIM_SWC0, SIM_SWC1,
SIM_SWC2, and SIM_SWC3)
These registers are general-purpose registers. They are reset only at power-on, so they can monitor
software execution flow.

6.3.3.1
This register is reset only by the Power-On Reset (POR). It is intended for use by a software developer to
contain data that will be unaffected by the other reset sources (external reset, software reset, and COP
reset).
6.3.4
Most Significant Half of JTAG ID (SIM_MSHID)
This read-only register displays the most significant half of the JTAG ID for the chip. This register reads
$01F2.
