When the XC87x 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 MBC, TMS and P0.0 collectively select the different boot options.
shows the available boot options in the XC87x.

MBC
1) In addition to the pins MBC, TMS and P0.0, TM pin also requires an external pull down for all the boot options.
2) BSL mode is automatically entered if no valid password is installed and data at memory address 0000H equals
3) If a device is programmed as LIN, LIN BSL is always used instead of UART/MultiCAN.
4) UART or MultiCAN BSL is decoded by firmware based on the protocol for product variant with MultiCAN. If no
5) In MultiCAN BSL mode, the clock source is switched to XTAL by firmware, bypassing the on-chip oscillator.
6) Alternate BSL Mode is a user defined BSL code programmed in Flash. It is entered if the AltBSLPassword is
7) Normal user mode with standard JTAG (TCK,TDI,TDO) pins for hot-attach purpose.
Note: The boot options are valid only with the default set of UART and JTAG pins.

MultiCAN and LIN variant, UART BSL is used.
This avoids any frequency invariance with the on-chip oscillator and allows other frequency clock input, thus
ensuring accurate baud rate detection (especially at high bit rates).
