Class1 power support
The device can control an external power amplifier (PA). Several signals are duplicated on
GPIOs for this purpose in order to avoid digital/analogue noise loops in the radio.
A software controlled register enables the alternate functions of GPIO[15:6] to generate the
signals for driving an external PA in a Bluetooth™ class1 power application.
Every bit enables a dedicated signal on a GPIO pin, as described in
Table 15.
rx_on is the same as the rx_on output pin. Not rx_on is the inverted signal, in order to save
components on the application board.
PA7 to PA0 are the power amplifier control lines. They are managed, on a connection basis,
by the baseband core. The Power Level programmed for a certain Bluetooth™ connection
is managed by the firmware, as specified in the Bluetooth™ SIG spec.
