Pulling resistors are internally connected to all digital input pins in radio transceiver
state P_ON (see section 7.1.2). Table 4-4 summarizes the pull-up and pull-down
configuration.
Table 4-4 Pull-Up/Pull-Down Configuration of Digital Input Pins in P_ON State
In all other radio transceiver states, no pull-up or pull-down resistors are connected to
any of the digital input pins.
Register 0x03 (TRX_CTRL_0)
The TRX_CTRL_0 register controls the drive current of the digital output pads and the
CLKM clock rate.
• Bit [7:6] – PAD_IO
The register bits PAD_IO set the output driver current of digital output pads MISO and
IRQ.
Table 4-5. Digital Output Driver Strength
• Bit [5:6] – PAD_IO_CLKM
The register bits PAD_IO_CLKM set the output driver current of pin CLKM.
