SPI Register Map
The values of all registers except read-only are set by default values after rest. The default values can be overrided by
accessing each register. Typical register values are subject to change and should be obtained from PTI. During normal
operation, SPI access should occur to address the following functions only.
z
Programming PLL hop frequency of BT_RF_PLL_CTRL0
z
Setting Tx power control value of BT_RF_TX_CTRL in the transmit mode
z
Reading receive signal strength indication of BT_RSSI_STA in the receive mode
z
Programming TXA or RXA of BT_RF_PLL_CTRL1 to indicate transmit or receive mode in bidirectional interface
