Freescale Semiconductor
Signal Descriptions
USBH2_FS
USB Host2 Full Speed output signal. This signal is multiplexed with CSPI2_SS[0] of CSPI2.
USBG_SCL
USB OTG I2C Clock input/output signal. This signal is multiplexed with SLCDC1_DAT8.
USBG_SDA
USB OTG I2C Data input/output signal. This signal is multiplexed with SLCDC1_DAT7.
USBG_TXR_INT
USB OTG transceiver interrupt input. Multiplexed with USBG_FS.
Secure Digital Interface
SD1_CMD
SD Command bidirectional signal—If the system designer does not want to make use of the internal pull-
up, via the Pull-up enable register, a 4.7k–69k external pull-up resistor must be added. This signal is
multiplexed with CSPI3_MOSI.
SD1_CLK
SD Output Clock. This signal is multiplexed with CSPI3_SCLK.
SD1_D[3:0]
SD Data bidirectional signals—If the system designer does not want to make use of the internal pull-up,
via the Pull-up enable register, a 50k–69k external pull-up resistor must be added. SD1_D[3] is muxed
with CSPI3_SS while SD1_D[0] is muxed with CSPI3_MISO.
SD2_CMD
SD Command bidirectional signal. This signal is multiplexed with SLCDC1_CS signal from SLCDC1.
SD2_CLK
SD Output Clock signal. This signal is multiplexed with SLCDC1_CLK signal from SLCDC1.
SD2_D[3:0]
SD Data bidirectional signals. SD2_D[3:2] are multiplexed with SLCDC1_RS and SLCDC_D0 signals
from SLCDC1.
