PD (Pull Up/Down Direction)
The resistor pull direction bit field (1 = pull-up, 0 = pull-down) for corresponding I/O lines that are set
by the PR command.
If the bit is set, the device uses an internal pull-up resistor. If it is clear, the device uses an internal
pull-down resistor. See the PR command for the bit order.
Parameter range
0x0 - 0x7FFF
Default
0x1FBF
RP(RSSI PWM Timer)
The PWM timer expiration in 0.1 seconds. RP sets the duration of pulse width modulation (PWM) signal
output on the RSSI pin. The signal duty cycle updates with each received packet and shuts off when
the timer expires.
When RP = 0xFF, the output is always on.
Parameter range
0 - 0xFF (x 100 ms)
Default
0x28 (four seconds)
DC (Device Controls)
Bit settings to enable or disable certain behaviors.
