Notice:
- In transition between TX and RX through Battery Saving Status, it takes more time to start the next
operation because of stopping the oscillation of XOSC.
Run à Battery Saving
6.9.3
TC32306FTG will move to Battery Saving by the setting of registers (h'0A[D7]ENB, h'0A[D6]ACT),
ENB pin or RESET pin. In RX, it is possible to move to Battery Saving by the use of AutoOff function.
Notice:
-
In TX, to move to Battery Saving under disabled PA is recommended. In order to reduce
unexpected signal transmission caused by the OFF timing gaps of each function blocks.
6.9.4
AutoOff Function
It is the function to move from Run (RX) to Battery Saving automatically without the register setting.
AutoOff functions are the type A and B. These are valid when Signal Detections are enabled.
Notice:
-
When to move to Battery Saving by AutoOff function, the value of registers (h'0A[D7]ENB,
h'0A[D6]ACT) will not change. Output and check Status_MONI signal at DET_TMONI1 pin
and/or DET_TMONI2 pin to confirm the transition to Battery Saving by this function.
-
About the pins behavior at the transition to Battery Saving by AutoOff, see Table 5-2.

AutoOff Type A (AutoOff by Signal Detections)
TC32306FTG will move from Run to Battery Saving if the determination of "No Signal Detection" is
indicated (Un_DET_out signal = "H"). It is valid to set register:h'10[D5]AutoOffA_en = "1".
