COEX_RXD
COEX_TXD
NOTE
Please note that COEX_RXD and COEX_TXD cannot be used as general UART.
3.10. Antenna Tuner Control
ANTCTL[0:3] and RFFE signals are used for antenna tuner control and should be routed to an
appropriate antenna control circuit. More details about the interface will be added in a future version of the
document.
