PNUM = 0x0C for embedded UART peripheral
The peripheral is not available at the [C] and at [N] supporting an interface. The size of both TX and RX buffers is 64 bytes.
The usage of the peripheral is limited in LP [Ns] because they regularly sleep in its main receiving loop. The peripheral works only when the device does not sleep or during a time defined by a ReadTimeout parameter of a Write & Read command. Please see the details below.
PIC HW UART peripheral interrupts can be handled at the Custom DPA Handler Interrupt event unless the DPA UART peripheral is not open or DPA UART Interface is not used.
