(1) NA in this table stands for "Not Applicable".
(2) Pins labeled as "No connect" must be left unconnected. Any connections to these pins may result in unpredictable behavior.
(3) Depending on the sys_clkreq direction the corresponding reset released state value can be:
– Z if sys_clkreq is used as input
– 1 if sys_clkreq is used as output
For a full description of the sys_clkreq control, see Power, Reset, and Clock Management chapter of the AM/DM37x Multimedia Device
Technical Reference Manual (literature number SPRUGN4).
(4) PU = [50 to 100 kΩ] per default or [10 to 50 kΩ] according to the selected mode. For a full description of the pull-up drive strength
programming, see the PRG_SDMMC_PUSTRENGTH configuration register bit field in the System Control Module chapter of the
AM/DM37x Multimedia Device Technical Reference Manual (literature number SPRUGN4). PD: 30 to 150 kΩ.
(5) The usage of this GPIO is strongly restricted. For more information, see the General-Purpose Interface chapter of the AM/DM37x
Multimedia Device Technical Reference Manual (literature number SPRUGN4).
(6) The drive strength is fixed regardless of the load. The driver is designed to drive 75Ω for video applications.
(7) In buffer mode, the drive strength is fixed regardless of the load. The driver is designed to drive 75Ω for video applications. In bypass
mode, the drive strength is 0.47 mA.
(8) The drive strength of these IOs is set according to the programmable load range: 2 pF to 4 pF per default or 4 pF to 12 pF. For a full
description of the drive strength programming, see the System Control Module chapter of the AM/DM37x Multimedia Device Technical
Reference Manual (literature number SPRUGN4).
(9) In the safe_mode_out1, the buffer is configured to drive 1.
(10) The pullup and pulldown can be either the standard LVCMOS 100-μA drive strength or the I2C pullup and pulldown described below:
Nominal resistance = 1.66 kΩ in high-speed mode with a load range of 5 pF to 12 pF, 4.5 kΩ in standard / fast mode with a load range
of 5 pF to 15 pF.
(11) The default buffer configuration is High-Speed I2C point-to-point mode using internal pullup. For a full description of the pull drive
strength programming, see prg_i2c1_pullupresx, prg_i2c1_lb1lb0, and prg_sr_pullupresx, prg_sr_lb bits of the CONTROL_PROG_IO1,
CONTROL_PROG_IO_WKUP1 control modules in the System Control Module / SCM Programming Model / Feature Settings section
and the System Control Module chapter of the AM/DM37x Multimedia Device Technical Reference Manual (literature number
SPRUGN4) to modify the IO settings if required by the targeted interface application.
(12) The default buffer configuration is standard LVCMOS mode (non-I2C). For a full description of the pull drive strength programming, see
PADCONFS bits of CONTROL_PADCONF_X control modules (standard LVCMOS mode), or prg_i2c2_pullupresx, prg_i2c2_lb1lb0, and
prg_i2c3_pullupresx, prg_i2c3_lb1lb0 bits of the CONTROL_PROG_IO2, CONTROL_PROG_IO3 control modules (I2C mode) in the
System Control Module chapter of the AM/DM37x Multimedia Device Technical Reference Manual (literature number SPRUGN4) to
modify the IO settings if required by the targeted interface application.
(13) Mux0 if sys_boot6 is pulled down (clock master).
