PR (Pull-up Resistor Enable) Command
<Serial Interfacing> The PR command is used to
set and read the bit field that is used to configure
internal the pull-up resistor status for I/O lines.
1 specifies the pull-up resistor is enabled. 0
specifies no pull up.
bit 0 - AD4/DIO4 (pin 11)
bit 1 - AD3/DIO3 (pin 17)
bit 2 - AD2/DIO2 (pin 18)
bit 3 - AD1/DIO1 (pin 19)
bit 4 - AD0/DIO0 (pin 20)
bit 5 - AD6/DIO6 (pin 16)
bit 6 - DI8 (pin 9)
bit 7 - DIN/CONFIG (pin 3)
For example: Sending the command ATPR 6F will turn bits 0, 1, 2, 3, 5 and 6 ON; and bits 4 & 7
will be turned OFF. (The binary equivalent of 0x6F is 01101111. Note that bit 0 is the last digit
in the bitfield.
PT (PWM Output Timeout) Command
<I/O Settings {I/O Line Passing}> The PT com-
mand is used to set/read the output timeout
value for both PWM outputs.
When PWM is set to a non-zero value: Due to I/O
line passing, a time is started which when expired
will set the PWM output to zero. The timer is reset
when a valid I/O packet is received.
RE (Restore Defaults) Command
<(Special)> The RE command is used to restore
all configurable parameters to their factory
default settings. The RE command does not write
restored values to non-volatile (persistent) memory. Issue the WR (Write) command subsequent
to issuing the RE command to save restored parameter values to non-volatile memory.
RN (Random Delay Slots) Command
<Networking & Security> The RN command is
used to set and read the minimum value of the
back-off exponent in the CSMA-CA algorithm. The
CSMA-CA algorithm was engineered for collision
avoidance (random delays are inserted to prevent
data loss caused by data collisions).
If RN = 0, collision avoidance is disabled during the first iteration of the algorithm (802.15.4 -
macMinBE).
CSMA-CA stands for "Carrier Sense Multiple Access - Collision Avoidance". Unlike CSMA-CD (reacts
to network transmissions after collisions have been detected), CSMA-CA acts to prevent data colli-
sions before they occur. As soon as a module receives a packet that is to be transmitted, it checks
if the channel is clear (no other module is transmitting). If the channel is clear, the packet is sent
over-the-air. If the channel is not clear, the module waits for a randomly selected period of time,
then checks again to see if the channel is clear. After a time, the process ends and the data is lost.
