System Integration Module (SIM)MCF5253 Reference Manual, Rev. 1Freescale Semiconductor 9-259.8.1 General Purpose InputsThere are 60 possible general purpose inputs. They can be read in registers GPIO-READ andGPIO-READ1. These bits reflect the logical value of the pin they are associated with. The GPIO-READand GPIO-READ1 registers always reflect the pin values, independent of the settings in theGPIO-FUNCTION, GPIO-EN, GPIO1-FUNCTION and GPIO1-EN registers. It does not matter if the pinis driving data out, or is being driven. The GPIO-READ and GPIO-READ1 bit to pin association isdetailed in Table 9-27.Table 9-27.
