5.2 Pin Behaviors at Reset and Register Initialized
Several pin behaviors of TC32306FTG depend on setting of Reset, register's initial value, or SPI Mode /
EEPROM Mode (including User Test). See Table 5-2.

Notice: In SPI Mode, TC32306FTG accepts the input of SPI settings at RESET = "L", but will not act.
In Battery Saving Status, DATA_IO pin behavior changes to the value of register:h'0A[D5]RX_TX. Initial
value of register:h'0A[D5]RX_TX is "0".
In Battery Saving Status, MISO pin changes its behavior at SPI Read when TC32306FTG is slave.
