Writing/erasing FLASH using SPM and EEPROM from
application not yet implemented in ATxmega devices (#7611)
Simulation is slow compared to other devices.
I/O view: Enabling the watchdog by setting ENABLE bits in WDT.CTRL register doesn't work
Attempting to change CLK.CTRL register through I/O view will cause Studio to hang (or mapped read-only in xmegaE5)
xmegaE5: TCCOM compare/capture register and TCxn_CTRLD read-only in I/O view
xmegaE5: FAULTn.CTRLG registers bit 5-7 read-only in I/O view
xmegaE5: SPI.DATA register read-only in I/O view
xmegaE5: CRC.DATAIN register read-only in I/O view
