IRQOVER=NORMAL, INOVER=NORMAL, OEOVER=NORMAL, OUTOVER=NORMAL, FUNCSEL=xip_sd0
GPIO control including function select and overrides.
| FUNCSEL | 0-31 -> selects pin function according to the gpio table 31 == NULL 0 (xip_sd0): undefined 5 (sio_32): undefined 31 (null): undefined |
| OUTOVER | 0 (NORMAL): drive output from peripheral signal selected by funcsel 1 (INVERT): drive output from inverse of peripheral signal selected by funcsel 2 (LOW): drive output low 3 (HIGH): drive output high |
| OEOVER | 0 (NORMAL): drive output enable from peripheral signal selected by funcsel 1 (INVERT): drive output enable from inverse of peripheral signal selected by funcsel 2 (DISABLE): disable output 3 (ENABLE): enable output |
| INOVER | 0 (NORMAL): don’t invert the peri input 1 (INVERT): invert the peri input 2 (LOW): drive peri input low 3 (HIGH): drive peri input high |
| IRQOVER | 0 (NORMAL): don’t invert the interrupt 1 (INVERT): invert the interrupt 2 (LOW): drive interrupt low 3 (HIGH): drive interrupt high |
