Digital Output Driver Configuration
The AT86RF231 provides a digital microcontroller interface. The interface comprises a slave
SPI (/SEL, SCLK, MOSI and MISO) and additional control signals (CLKM, IRQ, SLP_TR, /RST
and DIG2). The microcontroller interface is described in detail in
Interface” on page
Additional digital output signals DIG1...DIG4 are provided to control external blocks, i.e. for
Antenna Diversity RF switch control or as an RX/TX Indicator, see

pulled-down to digital ground (DIG1/DIG2) or analog ground (DIG3/DIG4).
The driver strength of all digital output pins (MISO, IRQ, DIG1, DIG2, DIG3, DIG4) and CLKM
pin can be configured using register 0x03 (TRX_CTRL_0), see
The capacitive load should be as small as possible as, not larger than 50 pF when using the
2 mA minimum driver strength setting. Generally, the output driver strength should be adjusted
to the lowest possible value in order to keep the current consumption and the emission of digital
signal harmonics low.
All digital input pins are internally pulled-up or pulled-down in radio transceiver state P_ON, see
Section 7.1.2.1 “P_ON - Power-On after VDD” on page
pull-up and pull-down configuration.
Table 1-4.
In all other radio transceiver states, no pull-up or pull-down circuitry is connected to any of the
digital input pins mentioned in
figuration is disabled.
