5.3.2 JTAG
JTAG uses the Serial Wire Debug (SWD) protocol and consists of the SWDIO and SWCLK lines.
Depending on the package of DA14531, the SWDIO signal is assigned to different pins (
Table 5 ).

5.3.3 SPI Data Flash (U2)
SPI data flash is enabled by default. The SPI data flash is the MX25R2035 from Macronix (2 Mbit)
and located on DA14531 PRO-MB.
Ext-SPI slave mode is used to connect DA14531 to SPI data flash.
The flash is absolutely isolated from the rest of the circuit unless appropriate jumpers are. The
configuration for SPI data flash is presented in
Table 6 .
