Register Descriptions
56F8367 Technical Data, Rev. 7.0
Freescale Semiconductor
117
Preliminary
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
$01D6.
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
$D01D.
Figure 6-7 Least Significant Half of JTAG ID (SIM_LSH_ID)
6.5.6
SIM Pull-up Disable Register (SIM_PUDR)
Most of the pins on the chip have on-chip pull-up resistors. Pins which can operate as GPIO can have these
resistors disabled via the GPIO function. Non-GPIO pins can have their pull-ups disabled by setting the
appropriate bit in this register. Disabling pull-ups 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
Table 2-2 to identify which pins can deactivate the internal pull-up resistor.
Figure 6-8 SIM Pull-up Disable Register (SIM_PUDR)
6.5.6.1
Reserved —Bit 15
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.5.6.2
PWMA1—Bit 14
This bit controls the pull-up resistors on the FAULTA3 pin.
