pulldown can be enabled or disabled by software.
§ _{Lv = Low voltage (1.65 V), Hv = High voltage (2.5 V)}
¶ _{A = Standard LVCMOS input/output}
G1 = Terminal may be gated by BFAIL
B = SUBLVDS input/ouput
G2 = Terminal may be gated by GPIO9 and MPUIO3
C = USB transceiver input/ouput
D = I²C input/output buffers
G3 = Terminal my be gated by BFAIL and OMAP5912 Internal Reset
H1 = Terminal may be 3-stated by BFAIL input
E = Analog oscillator terminals
H3 = MCSI1.DOUT pin can be forced into a high-impedance
F = Boundary-scannable terminal
state by the OMAP5912 HIGH_IMP3 control bit
K = Output buffer includes a serial resistor of 20 Ω to match with PCB line impedance and ensure proper signal integrity
# _{Z = High-Impedance, LZ = Low-Impedance (pin is driven), 1 = Output driven high, 0 = Output driven low}
NOTES: 3. NA denotes no multiplexing on the ball
4. ‘Regx’ denotes the terminal multiplexing register that controls the specified terminal where Regx = FUNC_MUX_CTRL_x
