The Transmit Register holds the 8 bits to be transmitted. Bit [7] of the Configuration Register must be set

(logic ‘1’) in order to use this. If Bit [7] is not set, use pin 6 to manually modulate the data.

The initial value of the register is AAh. This can be used to send a preamble signal by setting Bit [5] of

the Power Management Register (See Figure 3 below). When this bit is set, transmission begins

immediately and the initial value AAh is sent. The SDO pin(4) may be monitored to see when the next

byte of data may be written to the register (SDO is logic ‘1’).

Initial Setup

TXEN = 0

Bit [15..8] - Command Code: These bits are the command code that is sent serially to the processor that

identifies the bits to be written to the Transmit Register.

Bit [7..0] – Transmit Byte: The data byte to be sent is written here. As soon as the power amplifier is

enabled the data byte is sent. The SDO pin(4) may be monitored to determine when the byte has been

sent.
