Preliminary
Figure 6-5 SIM Software Control Register 0 (SIM_SCR0)
6.5.3.1
Software Control Data 1 (FIELD)—Bits 15–0
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).
6.5.4
Most Significant Half of JTAG ID (SIM_MSH_ID)
This read-only register displays the most significant half of the JTAG ID for the chip. This register reads
$01F4.
Figure 6-6 Most Significant Half of JTAG ID (SIM_MSH_ID)
6.5.5
Least Significant Half of JTAG ID (SIM_LSH_ID)
This read-only register displays the least significant half of the JTAG ID for the chip. This register reads
$601D.
Figure 6-7 Least Significant Half of JTAG ID (SIM_LSH_ID)
6.5.6
SIM Pullup Disable Register (SIM_PUDR)
Most of the pins on the chip have on-chip pullup resistors. Pins which can operate as GPIO can have these
resistors disabled via the GPIO function. Non-GPIO pins can have their pullups disabled by setting the
appropriate bit in this register. Disabling pullups is done on a peripheral-by-peripheral basis (for pins not
muxed with GPIO). Each bit in the register (see Figure 6-8) corresponds to a functional group of pins. See
