Hallo everyone, I'm trying to use the Interrupt Service Routine for the UART RX on my PIC32MZ0512EFE064 but seems it doesn't starts when I send a byte to it. Following my example code:

// Configuration Bit settings
// SYSCLK = 80 MHz

Hi guys. I'm about to embark on the epic journey of using the MZ EF, and I have a few questions:1) there are 7 shadow register sets. There are 7 priorities. Does it matter which shadow reg you use for a given priority? Is there a catch? Seems they should ..

What is the settling time of the 5-bit DAC of the PIC32MM devices?I am using a PIC32MM0064GPL028 and cannot find such info neither in the datasheet nor in the FRM.On the scope I see rising time much bigger than falling one...
