Note
Please refer to the application note "AN0002 EFM32 Hardware Design Considerations" for
guidelines on designing Printed Circuit Boards (PCB's) for the EFM32LG232.
4.1 Pinout
The EFM32LG232 pinout is shown in Figure 4.1 (p. 44) and Table 4.1 (p. 44). Alternate locations
are denoted by "#" followed by the location number (Multiple locations on the same pin are split with "/").
Alternate locations can be configured in the LOCATION bitfield in the *_ROUTE register in the module
in question.
