1. See Help > Readme menu item for an updated description of program features.

2. See revision history at bottom of this file.

3. See User's Guide on this Wiki page:

   http://processors.wiki.ti.com/index.php/Pin_Mux_Utility_for_ARM_MPU_Processors_v2

4. Supports the following devices:
   AM335x
   AM3505, AM3517
   AM3703, AM3715
   AM3871, AM3872, AM3874 
   AM3892, AM3894, 
   C6A8167, C6A8168
   DM3725, DM3730
   DM8165, DM8166, DM8167, DM8168, 
   OMAP3503, OMAP3515, OMAP3525, OMAP3530

5. Includes IO power domain voltage display and checking for peripheral interfaces that are not all using the same
   IO cell supply voltage. (AM335x only) Not checked for MISC or GLUE interfaces.

6. Includes Multi-Muxed Violation status for peripheral interfaces (for all supported devices).  This applies to cases where the same 
   internal signal is muxed to multiple ball locations.  A violation is flagged if the signal is selected at more than one ball location.

7. Includes use of pre-defined IO Sets (AM335x only).  Instead of allowing selection of any set of interface member signals,
   limited pre-defined sets of interface member signals are allowed.  The tool loads IO Sets information for the device and uses this
   to guide the user into using a tested configuration that meets timing requirements.  Either all or a subset of the interface member 
   signals specified by an IO Set may be selected.  

8. Special restrictions that apply to the AM335x Device:

   MCASP0 Interface
	MCASP0 IO sets are timing closed for OPP100 condition only. OPP50 is not supported.
	McASP0 IO Set1-5 supports only 3.3V IO voltage
	McASP0 IO Set6 Supports only 1.8V IO
	McASP0 IO Set8 Supports only 3.3V IO
	McASP0 IO Set12 Supports only 3.3V IO	

   MCASP1 Interface
	McASP1 IO sets are timing closed for OPP100 condition only. OPP50 is not supported.
	McASP1 IO Set1 supports only 3.3V IO
	McASP1 IO Set2 supports only 1.8V IO
	McASP1 IO Sets 4 to 10 Supports only 1.8V IO

   MMC0, MMC1, MMC2 Interfaces 
	Only Standard (STD) and High Speed (HS) modes are supported. New SDR12, SDR25, SDR50 modes as defined in SD3.0 spec are not supported.

   GEMAC_CPSW Interface
	MII Mode Not Supported for OPP50 Condition.   Will update after Timing Closure is complete.
	RGMII Mode Not Supported for OPP50 Condition
	RMII Mode Not Supported for OPP50 Condition

9. Pad Configuration Parameters.
   Input Enable parameter (IDIS or IEN).  This parameter is defaulted based on the current mux selection 
   for the pad which determines the current I/O direction (I, O or I/O).  This parameter should not need 
   to be editted in most cases.  For all signals that have I/O capability, the input enable bit will 
   default to 1 (IEN).

   However, some signals with I/O capability need to be used as output only depending on 
   how the hardware module itself is configured.  If the ball needs to be configured as output,
   the Input Enable pad configuration bit is recommended to be changed to IDIS.

   Also, most GPIO signals have I/O capability.  If used as output only, the Input Enable bit is
   recommended to be set to IDIS.   


10. Other Pad Configuration Parameters.

   Active-Mode Internal Pull defaults to a setting specified in the device model for each ball.

   Standby-Mode Internal Pull defaults to PI (pull-inhibited) for all signals.  

   Active-Mode Internal Pull and Standby-Mode Internal Pull settings may need to be editted depending on
   pull-up or pull-down resistors that are present in the schematic design.

   Standby Configuration defaults to SIG (output latched signal state) for all signals.

   Wake Up Input Enable defaults to disabled for all signals.

   These parameters need to be editted on a ball-by-ball basis.  Groups of balls can be editted 
   to the same setting together if multiple cells in Pad Config column are selected.

11.In AM35xx device model CSV file, corrected offset for CONTROL_PADCONF_SDRC_CKE0 from
   0x0262 to 0x0266.
