J46
J46 is NOPOP but is compatible to same
connector on Nordic development board and
brings out same signals.
SIO_41 on BL654PA is SPI_CLK (as an
alternative function) is disconnected from J46 on
devboard by open solderbridge SB23.
SIO_41 on BL654PA is directly connected to U2
(Eeprom) pin6 on devboard.

Routed to FTDI: No Jumper in J35 (default).
Routed to Atmel: Fit Jumper in J35.
Jumper in J35 selects between BL654PA UART
