After the frame transmission has completed, the Atmel AT86RF232 automatically turns
off the power amplifier, generates an IRQ_3 (TRX_END) interrupt and returns into
PLL_ON state.
7.1.2.7 RESET State
The RESET state is to reset all registers and state machines of the AT86RF232 to their
default values, exception are register bits CLKM_CTRL (register 0x03, TRX_CTRL_0).
These register bits require a specific treatment, for details see
Section
9.6.4.
A reset forces the radio transceiver into TRX_OFF state. If the device is still in the
P_ON state it remains in the P_ON state though.
A reset is initiated with pin 8 (/RST) = L and the state is left after setting /RST = H. The
reset pulse should have a minimum length as specified in
Section 12.4
see parameter
t

During reset the microcontroller has to set the radio transceiver control SLP_TR and
/SEL pins to their default values.
An overview about the register reset values is provided in
Table
14-2.
