FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not
available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages.
MODE
USB LBP mode, normal mode, test mode selection & anti-
fuse bias. During evaluation and testing, the IC can be
configured for normal operation or test mode via the MODE
pin as summarized in the following table.
GNDCTRL
Ground for control logic.
SPIVCC
Supply for SPI bus and audio bus
CS
CS held low at Cold Start configures the interface for SPI
mode. Once activated, CS functions as the SPI Chip Select.
CS tied to VCORE at Cold Start configures the interface for
I2C mode; the pin is not used in I2C mode other than for
configuration.
Because the SPI interface pins can be reconfigured for
reuse as an I2C interface, a configuration protocol mandates
that the CS pin is held low during a turn on event for the IC (a
weak pull-down is integrated on the CS pin).
CLK
Primary SPI clock input. In I2C mode, this pin is the SCL
signal (I2C bus clock).
MOSI
Primary SPI write input. In I2C mode, the MOSI pin hard
wired to ground or VCORE is used to select between two
possible addresses (A0 address selection).
MISO
Primary SPI read output. In I2C mode, this pin is the SDA
signal (bi-directional serial data line).
GNDSPI
Ground for SPI interface.

Notes
47.
Time slots may be included for blocks which are defined by the PUMS pins as disabled, to allow for potential activation.
48.
The following supplies are not included in the matrix, since they are not intended for activation by the start-up sequencer: VCAM,
VGEN1, VGEN3, VVIDEO, and VAUDIO. SWBST is not included on the PUMS2 = Open column
49.
USB supplies VUSB, is only enabled if 5.0 V is present on UVBUS.
50.
SWBST = 5.0 V, powers up, as does VUSB, regardless of the 5.0 V present on UVBUS. By default VUSB will be supplied by SWBST.
