Table General Purpose Input/Output (GPIO)-22 and Table General Purpose Input/Output (GPIO)-24 show
registers that select I/O pins, Table General Purpose Input/Output (GPIO)-23 and Table General Purpose
Input/Output (GPIO)-25 show selectable I/O pins. Initial value of a register is set as 63. In this case, no I/O pin is
selected and an input value to the circuit for detecting interrupts or events is tied to “0”.
As for the selected external interrupt I/O pin, the Input Enable needs to be valid by setting 1 on the register
IO_*.ENZI
