If either EMU_KEY or EMU_BMODE
are invalid, the “wait” boot mode is
used. These values can then be
modified using the debugger and a
reset issued to restart the boot process

In emulation boot mode, first the EMU_KEY register is checked to see if it has a value of
0x55AA. If either EMU_KEY or EMU_BMODE are invalid, the wait boot mode is used. These
values can then be modified using the debugger and a reset issued to restart the boot process.
This can be considered the default on power-up. At this point, you would like the device to wait
until given a boot mode.
If EMU_KEY register has a value of 0x55AA, then the hex value in the EMU_BMODE register
determines the boot mode. The boot modes are parallel I/O, SCI, SPI, I2C, OTP, CAN,
M0SARAM, FLASH, and Wait. In addition, there is a GetMode, which emulates the stand-alone
boot mode.
