More information is given in the Application Note “Power Management Using the
Embedded Stand-alone Wake-up Mode Protocol. Rev. 2” reference 2186.
The application microcontroller can control and monitor the AT86RF211S through a syn-
chronous, bi-directional 3-wire serial interface, comprising three signals:
When SLE = 1, the interface is inhibited and the SCK and SDATA (in) values are not
propagated into the IC, reducing power consumption and preventing any risk of parasitic
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 during one access cycle, meaning that only one regis-
ter can be either read or written.
A message comprises three fields:
A variable register length and partial read or write cycles are supported.
In the case of partial read or write cycles, the first data (in or out) is always the register’s
MSB.
• SLE signal: enable input
• SCK signal: clock input
• SDATA signal: data in/out
• Address A[3:0]: 4 bits (MSB first)
• R/W: read/write selection
• Data D[31:0]: up to 32 bits (MSB first)
