Note: SERCOM4/SERCOM5 are not available on the VQFN32/TQFP32 packages. All analog pin functions are on the peripheral function 03. The peripheral function 03 must be selected to disable the digital control of the pin. Only some pins can be used in SERCOM I²C mode. Refer to the Type column for using a SERCOM pin in I²C mode. Refer to the Electrical Characteristics chapter for details on the I²C pin characteristics. TC6 and TC7 are not supported on the PIC32CM[3204/1602]GV032 (32-pin) and PIC32CM[3204/1602]GV048 (48-pin) devices. Refer to the Configuration Summary for details. The SWDIO function is only activated in the presence of a debugger.

Note: SERCOM4/SERCOM5 are not available on the VQFN32/TQFP32 packages. All analog pin functions are on the peripheral function 03. The peripheral function 03 must be selected to disable the digital control of the pin. Only some pins can be used in SERCOM I²C mode. Refer to the Type column for using a SERCOM pin in I²C mode. Refer to the Electrical Characteristics chapter for details on the I²C pin characteristics. TC6 and TC7 are not supported on the PIC32CM[3204/1602]GV032 (32-pin) and PIC32CM[3204/1602]GV048 (48-pin) devices. Refer to the Configuration Summary for details. The SWDIO function is only activated in the presence of a debugger.
