MOTOROLA
General Purpose I/Os
Note: The CMD_SDIO2, SDATA0_SDIO1, RSTO/SDATA2_BS2, A25, QSPI_CS1,
QSPI_CS3, SDRAM_CS2, EBUOUT2, BUFENB2, SUBR, SFSY, RCK, SRE,
LRCK3, SWE, and the SCLK3 signals are only used in the 160 MAPBGA
package.
Note: MCLK1 and MCLK2 will output a clock signal just after reset and before they can be
configured as GPIO if so desired. The frequency of the clock will be the same as
CRIN prior to initialization of the PLL.
