uart_2478 templete not enabling RX and Fault Interrupts

[ikerperezdelpalomar]

Hi,

After generating code with the MCC for the UARTS configured as non-blocking mode I could not find the section of the code in which the rx and fault interrupts were enabled ( I was looking for IEC3SET = _IEC3_U1EIE_MASK; and IEC3SET = _IEC3_U1RXIE_MASK;). After digging for some time I decided to change the operation mode to ring buffer, because it should also generate the interrupts, and in this case in this enable them, in the end of the UART_Initialization() function. I tried multiple times to upload

MCU used: pic32MZ2064DAH176
