Driver Strength Settings
Pulling transistors (10µA current source) are internally connected to all digital input pins in radio transceiver state P_ON, including reset during P_ON.
The table below summarizes the pull-up and pull-down configuration.
| Pin | H = pull-up, L = pull-down |
|---|---|
| /RST | H |
| /SEL | H |
| SCLK | L |
| MOSI | L |
| SLP_TR | L |
In all other radio transceiver states, including RESET, no pull-up or pull-down transistors are connected to any of the digital input pins mentioned in the table above.
Note: In all other states, external circuitry should guaranty defined levels at all input
pins. Floating input pins may cause unexpected functionality and increased power
consumption, for example in SLEEP state.
If the additional digital output signals DIG1, …, DIG4 are not activated, these pins are pulled-down to digital ground (DIG1/DIG2) or analog ground (DIG3/DIG4).
