Hi, jmF,
The boot option available on the cpu board is for user to try out the different boot modes as what you have listed in Table 3. The description of the various boot mode can be found in chapter 26 of the XMC4500 reference manual. P1.4 and P1.5 will provide the receive (COM_RXD) and transmit (COM_TXD) signals for ASC BSL and CAN BSL.
