Note:
The power can then be adjusted, from the value set by R
12 dB below, by programming the bits 6 to 8 of the CTRL1 register. So, 8 levels are dig-
itally selectable with a variation of the output power. The minimum regulated output
power is set to -10 dBm.
Table 3. Software Control of the Power Level
Note:
The application microcontroller can control and monitor the AT86RF211 through a syn-
chronous, bidirectional, serial interface made of 3 wires:
•
•
•
When SLE = ‘1’, the interface is inhibited, i.e. the SCK and SDATA (in) values are not
propagated into the IC, reducing the power consumption and preventing any risk of par-
asitic write or read cycle.
A “read” or “write” cycle starts when SLE is set to ‘0’ and stops when SLE is set to ‘1’.
Only one operation can be performed in one access cycle: only one register can be
either read or written.
TXLVL (CTRL1)
SLE: enable input
SCK: clock input
SDATA: data in/out
Keeping the PA output matched guarantees maximum power efficiency.
