All other register values (channel, power, ...) of the radio transceiver will not be affected by this procedure.
In order to ensure, that the radio transceiver is not in one of the *_NOCLK states, the pin TRX_PIN_SLP_TR is set to LOW, before CMD_FORCE_TRX_OFF is written.
trx_pinset_slptr(0); delay_us(6); trx_bit_write(SR_TRX_CMD, CMD_FORCE_TRX_OFF); delay_us(6); state = trx_bit_read(SR_TRX_STATUS); ASSERT(state==TRX_OFF);
