ModelNumber
- this parameter specifies the DNT model, in this case a DNT90M.
OtaTxQueueBusy
- this parameter indicates if the transmitter queue is currently holding bytes to transmit. If bytes are pre-
sent in the queue the value is 1. If the queue is empty the value is 0.

SerialParams
- this parameter sets the serial mode options for parity and stop bits:
Setting Mode
0x00
No parity, 8 data bits, 1 stop bit (default)
0x01
No parity, 8 data bits, 2 stop bits
0x02
Reserved
0x03
Reserved
0x04
Even parity, 8 data bits, 1 stop bit
0x05
Even parity, 8 data bits, 2 stop bits
0x06
Odd parity, 8 data bits, 1 stop bit
0x07
Odd parity, 8 data bits, 2 stop bits
Note that 8-bit data with no parity is capable of carrying 7-bit data with parity for compatibility without loss of generality for
legacy applications that may require it.
SpiMode - this parameter sets the SPI operating mode:
Setting Mode
0x00
SPI disabled - serial UART mode (default)
