63 / 235 page ![]() RT3050/52 Datasheet Preliminary Revision August 14, 2008 DSR3050/52_V.2.0_081408 -63- Form No.:QS-073-F02 Rev.:1 Kept by: DCC Ret. T ime: 5 Years 11:0 R/W PIOPOL [11:0] Program I/O Pin Polarity These bits are used for controlling the polarity of the data driven on or read from the PIO pins. To invert the polarity of the data at any PIO pin, the corresponding bit should be set to ‘1’; a value of ‘0’ will not modify the pin data. Note: The polarity controls affect both input and output modes. 12’b0 GPIO51_40_SET:Set PIO Data Bit (offset: 0x7C) Bits Type Name Description Initial value 23:12 - - Reserved 20’b0 11:0 R/C PIOSET [11:0] These bits are used for clearing bits in the PIODATA output register. Writing a ‘1’ will clear the corresponding bit in the PIODATA r egister. Writing a ‘0’ will have no effect. 12’b0 GPIO51_40_RESET:Clear PIO Data bit (offset: 0x80) Bits Type Name Description Initial value 23:12 - - Reserved 20’b0 11:0 R/C PIORESET [11:0] These bits are used for setting bits in the PIODATA output register. Writing a ‘1’ will set the corresponding bit in the PIODATA register. Writing a ‘0’ will have no effect. 12’b0 GPIO51_40_TOG:Toggle PIO Data bit (offset: 0x84) Bits Type Name Description Initial value 23:12 - - Reserved 20’b0 11:0 R/C PIOTOG [11:0] These bits are used for toggling bits in the PIODATA output register. Writing a ‘1’ will invert the corresponding bit in the PIODATA r egister. Writing a ‘0’ will have no effect. 12’b0 |
