17 / 235 page  RT3050/52 Datasheet Preliminary Revision August 14, 2008 DSR3050/52_V.2.0_081408 -17- Form No.：QS-073-F02 Rev.：1 Kept by： DCC Ret. T ime： 5 Years 1.3 Pins Sharing Scheme Some pins are shared with GPIO to provide maximum flexibility for system designers. The RT3050/52 provides up to 52(RT3052)/22(RT3050) GPIO pins. Users can configure SYSCFG and GPIOMODE registers in the System Control block to specify the pin function. Unless it specified explicitly, all the GPIO pins are in input mode after reset.
