† I = Input, O = Output, Z = High-Impedance

‡ PD20 = 20-

µA internal pulldown, PD100=100-µA internal pulldown, PU20 = 20-µA internal pullup, PU100 = 100-µA internal pullup. Pullup or

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

G3 = Terminal my be gated by BFAIL and OMAP5912 Internal Reset

D = I2C input/output buffers

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
