1 # This definition describes processor architecture.
2 # Valid value: efr32 for EFR32 based boards
5 # This describes the sub-architecture of the processor. Allowed values are
6 # following: xg12,xg21,xg22
9 # This definitions describes the processor memory variant. It is only used when
10 # <code>@ref config_mk_mcu "MCU"</code> is <code>efr32</code>.
11 # Valid values are following:
12 # - <code>pxxxf512</code> For 512 kB flash memory variant (xg12)
13 # - <code>xxxxf512</code> For 512 kB flash memory variant (xg22)
14 # - <code>pxxxf1024</code> For 1024 kB flash memory variant (xg12)
15 # - <code>xxxxf1024</code> For 1024 kB flash memory variant (xg21)
18 # This describes the hardware capabilities of the board
19 # (this is used to customize the hardware service of the bootloader).
