Forcing the SDIO Line to the Hi-Z State
There are times when the SDIO line from the ADNS-2610

line will go into a Hi-Z state, because the SDIO pin was
configured as an input. However, if the last operation from

down mode by writing to the configuration register.
Then, the power-down mode can stay activated, with the
ADNS-2610 in the shutdown state, or the power-down
mode can be deactivated, returning the ADNS-2610 to
normal operation. In both conditions, the SDIO line will
go into the Hi-Z state.
