3.7.2
When the XC864 is reset, it must identify the type of configuration with which to start the
different modes once the reset sequence is complete. Thus, boot configuration
information that is required for activation of special modes and conditions needs to be
applied by the external world through input pins. After power-on reset or hardware reset,
the pins TMS and P0.0 collectively select the different boot options.
available boot options in the XC864.
Note: The boot options are valid only with the default set of UART and JTAG pins.

In XC864, User Mode is entered through the BSL Mode. The entry also depends on the
type of Flash protection
defined parameter as described in each type of user mode entry.
There are three types of User Mode entry. Each entry was designed to be used under
different situations.

User Mode is enterd via BSL Mode depends on the user-parameter No_Activity_Count(NAC) and the Flash
protection.
Flash protection has to be taken and use with proper care as it will directly impact the usage of BSL mode and
entry to User Mode. Refer to the 3 types of User Mode entry for detail descriptions.
Flash protection can be enabled or disabled by installing the user PASSWORD via BSL mode 6.
