LTE-A Module Series
EM160R-GL_Hardware_Design 44 / 73
3.9. COEX UART
*
The module provides one COEX UART.
Table 22: Pin Definition of COEX UART
Please note that COEX_RXD and COEX_TXD cannot be used as general UART.
3.10. Antenna Tuner Control Interfaces
*
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.
