D.1
DA14531 WLCSP17 PRO-DB, GPIOs Configuration, and R-matrix
D14531 WLCSP PRO-DB provides six pins. To serve all the available functions, a resistor matrix (R-
Matrix) is applied to DA14531 WLCSP PRO-DB.
Signal multiplication is completed with signal selection header (J1) on PRO-MB.
Functions available for DA14531 WLCSP17 PRO-DB are the SPI data bus, JTAG, Reset, UART, and
XTAL32K.
The default setup for the D14531 WLCSP17 PRO-DB is: Reset, JTAG, and SPI data bus (assigned
to SPI data flash).
