All digital I/O's (with the exception of SDIO signals) are Hi-Z when the device is in shutdown mode with internal PU/PD according to the "shutdown state" column.
See software release notes for support level.
LOGGER and HOST_IRQ_WL pins are sensed by the device during boot, see CC33xx Hardware Integration.
