When the PIT interrupt is triggered a message a printed on the UART terminal and an LED is toggled on the board.</P> <P class="lia-align-justify">It may be useful to try it out, and then made some changes according to what you need.</P> <P class="lia-align-justify">Best regards, Raul.</P> Thu, 22 Dec 2022 20:37:33 GMT https://community.nxp.com/t5/LPC-Microcontrollers/Using-MRT-in-with-LPC845-brk/m-p/1573891#M51084 RaRo 2022-12-22T20:37:33Z
