Write link policy.
The link policy can be chosen to optimize the link for a speci-
fic application. The link policy can be chosen to reduce
power consumption, get faster response times, increase the
range or to optimize the SPA as either sender or receiver.
Note!
Using other link policies than the default may lead to intero-
perability problems. Verify that the chosen link policy works
with other devices your application is intended to interope-
rate with. If not, use the default link policy.
Link policy 3,4,10,12 gives the shortest response times.
Link policy 8 combined with stop mode (AMPM: 3) gives the
lowest power consumption.
When using a baud rate of 460 kbps or more on the serial in-
terface, a combination of link policy 2 on the sender and link
policy 1 on the receiver gives the highest throughput. When
using a slower baud rate, then the default link policy gives
equally high throughput.
If the remote device rejects the link policy requested by the
SPA, then the red LED gives an error indication. If the remote
device rejects the link policy, then the default link policy is
used.
