1.3 Digital Pins
The Atmel AT86RF233 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 Chapter 6.
Additional digital output signals DIG1, …, DIG4 are provided to control external blocks,
that is for Antenna Diversity RF switch control or as an RX/TX Indicator, see
Section 11.4 and Section 11.5 respectively.
1.3.1 Driver Strength Settings
The driver strength of all digital output pins (MISO, IRQ, DIG1, …, DIG4) and CLKM pin
are fixed. The capacitive load should be as small as possible as, not larger than 50pF.
1.3.2 Pull-up and Pull-down Configuration
Pulling transistors are internally connected to all digital input pins in radio transceiver
states P_ON (including reset during P_ON) and DEEP_SLEEP, refer to Section 7.1.2.1
and Section 7.1.2.4.
Table 1-3 summarizes the pull-up and pull-down configuration.

Note: 1. Except SLP_TR pin for DEEP_SLEEP state.
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 Table 1-3.
Note:
2. 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).
