TX_IN

W
Undefined
CXPI transmitter input ('tx_in', 'cxpi_tx_in' in functional
mode). TX_IN and RX_IN can be used to determine a
wakeup source. Note that wakeup source detection
relies on the external transceiver functionality.

Undefined
CXPI receiver input ('rx_in', 'cxpi_rx_in' in functional

1
CXPI transceiver enable ('en_out', 'cxpi_en_out'). This
field controls the enable (or low active sleep enable) of
the external transceiver:
'0': Disabled.
'1': Enabled.
If CTL0.AUTO_EN is '0', SW controls this field to
enable the external transceiver. If CTL0.AUTO_EN is
'1', HW controls this field to enable the external
transceiver:
- HW sets this field to '1' when it is out of Sleep state. If
it moves to Sleep state, HW will clear this field to '0'.
