Throughout a sleep cycle the direction of the DIO, and the state of the outputs, is held. This is based on the resultant
of the GPIO Data/ Direction registers and the effect of any enabled peripherals at the point of entering sleep.
Following a wake-up these directions and output values are maintained under control of the GPIO data / direction
registers. Any peripherals enabled before the sleep cycle are not automatically re-enabled, this must be done through
software after the wake-up.
For example, if DIO0 is configured to be SPISEL1 then it becomes an output. The output value is controlled by the
SPI functional block. If the device then enters a sleep cycle, the DIO will remain an output and hold the value being
output when entering sleep. After wake-up the DIO will still be an output with the same value but controlled from the
GPIO Data/Direction registers. It can be altered with the software functions that adjust the DIO, or the application may
re-configure it to be SPISEL1.
Unused DIO pins are recommended to be set as inputs with the pull-up enabled.
