Antenna match
(Depends on type of
antenna)
HOST INTERFACE
(Do not leave nHIB floating.
Always connect to host)
40MHz, ESR < 50, CL = 8pF, 20ppm
Consider adding extra decoupling capacitors
if the battery cannot source the peak currents.
Flash programming
(Connect TP to UART, nRESET
to be driven by external programmer)
RTS/CTS optional
Needed only when using
UART as host interface
