2.5 Supported AFEs

The metrology library supports the following AFEs, depending on the MCU in use:

• The PIC32CXMTSH supports only its internal AFE, the ATSENSE203, which provides 2 voltage and 2 current channels.
• The PIC32CXMTC supports the ATSENSE301 (offering 3 voltage and 4 current channels) as well as select devices from the MCP391x family. The specific MCP391x devices supported are listed in the description of the AFE_SELECTION register.
