Reference Usage Comments Image
S1 JTAG

When set to ‘MIPI’ position, the JTAG interface is routed to the MIPI 60-pin connector (J19).

When set to ‘XDS’ position, the JTAG interface is routed to the XDS110 USB interface (J8)

S2 SPI

When set to ‘PMIC_SPI’ position, the MSS_SPIB interface is routed to the PMIC and to the J16 header. 1

When set to ‘DBG_SPI’, the MSS_SPIB interface is routed to the 60-pin debug header (J7)
