D.2 DA14531 FCGQFN24 PRO-DB, GPIOs Configuration, and R-matrix
DA14531 FCGQFN24 PRO-DB provides 12 pins. To serve all the available functions, a resistor
matrix (R-Matrix) is applied to DA14531 FCGQFN24 PRO-DB.
Signal multiplication is completed with the signal selection headers (J1, J8, and J19) on PRO-MB.
Functions available for DA14531 FCGQFN24 PRO-DB are the SPI data bus, JTAG, Reset, UART,
XTAL32K, LED, Key, and extension ports (mikroBUS and Arduino).
The default setup for the D14531 FCGQFN24 PRO-DB is: Reset, JTAG, and SPI data bus (assigned
to SPI data flash), single-wire UART, LED and a Key. Extension ports use multiplexed signals.
Figure 66 and Table 19 show the resistor matrix for FCGQFN24.
