1. How to control S605-32’s REG ?

   • S605-32’s GPIO A-E Multi Function Control Register address mapping:

     GPAFUN = 0xB000_0000 + 0x80
     GPBFUN = 0xB000_0000 + 0x84
     GPCFUN = 0xB000_0000 + 0x88
     GPDFUN = 0xB000_0000 + 0x8C
     GPEFUN = 0xB000_0000 + 0x90
   • You can use nvtio to read/write REG.
   • ex. read 0xB0000080 ==> nvtio 0xB0000080

   • ex. write 0xB0000080 ==> nvtio -w 0xB0000080 0x00000001
