If
LT
=
0
, the device uses the default blink rate: 500 ms for a sleep coordinator, 250 ms for all other
nodes.
For all other
LT
values, the firmware measures
LT
in 10 ms increments.
Parameter range
0, 0x0A - 0xFF (100 - 2550 ms)
Default
0
PR (Pull-up/Down Resistor Enable)
The bit field that configures the internal pull-up/down resistor status for the I/O lines. If you set a
PR
bit to 1, it enables the pull-up/down resistor; 0 specifies no internal pull-up/down resistor. The
following table defines the bit-field map for
PR
command.
PR
and
PD
only affect lines that are configured as digital inputs or disabled.
The following table defines the bit-field map for
PR
and
PD
commands.
