or as MISO/MOSI at the same GPIOs, as shown in the diagram below:
The following SPI1/2 signals can alternatively be assigned at the GPIOs (alternate func-
tions) in line with SPI_MODE (see 2.3.10.9.20):
SPI1 SPI2
GPIO16(A), GPIO40(C) GPIO12(C), GPIO24(A),
GPIO17(A), GPIO41(C) GPIO13(C), GPIO25(A),
GPIO18(A), GPIO42(C) GPIO14(C), GPIO26(A),
GPIO19(A), GPIO43(C) GPIO15(C), GPIO27(A),
