Interface Data Rate. Set/Read the serial interface data rate for communications
between the RF module serial port and host.
Request non-standard baud rates with values above 0x80 using a terminal window.
Read the BD register to find actual baud rate achieved.
0 - 7 (standard baud rates)
0 = 1200 bps
1 = 2400
2 = 4800
3 = 9600
4 = 19200
5 = 38400
6 = 57600
7 = 115200
0x80 - 0x3D090
(non-standard baud rates up to
250 Kbps)

Serial
Interfacing
Packetization Timeout. Set/Read number of character times of inter-character delay
required before transmission. Set to zero to transmit characters as they arrive instead of
buffering them into one RF packet.
0 - 0xFF [x character times] 3

API Enable. Disable/Enable API Mode.
0 - 2
0 =Disabled
1 = API enabled
2 = API enabled (w/escaped
control characters)

Parity. Set/Read parity settings.
0 - 4
0 = 8-bit no parity
1 = 8-bit even
2 = 8-bit odd
3 = 8-bit mark
4 = 8-bit space

Pull-up Resistor Enable. Set/Read bitfield to configure internal pull-up resistor status
for I/O lines
Bitfield Map:
bit 0 - AD4/DIO4 (pin11)
bit 1 - AD3 / DIO3 (pin17)
bit 2 - AD2/DIO2 (pin18)
bit 3 - AD1/DIO1 (pin19)
bit 4 - AD0 / DIO0 (pin20)
bit 5 - RTS / AD6 / DIO6 (pin16)
bit 6 - DTR / SLEEP_RQ / DI8 (pin9)
bit 7 - DIN/CONFIG (pin3)
Bit set to “1” specifies pull-up enabled; “0” specifies no pull-up
