Hardfault observed when HFXT 4MHz used as MCLK with debugger connected
When MCLK is configured to be HFXT 4MHz with the configurations of: HFXTRSEL set to 0 (recommended value for crystal of 4 to 8 MHz range), the program can jump to hard fault or NMI at random.
Set HFXTRSEL value to 1 or higher (8MHz to 48MHz range) when debugging the code with HFXT 4MHz as the MCLK.
