Bootstrap Loader
The XC886/888 includes a Bootstrap Loader (BSL) Mode that can be entered with the
pin configuration shown in
during hardware reset. The main purpose of BSL
Mode is to allow easy and quick programming/erasing of the Flash and XRAM via serial
interface. The XC886/888 supports three device BSL modes:
•
UART BSL
•
LIN BSL
•
MultiCAN BSL
If a device is programmed as LIN, LIN BSL is always entered (even if the MultiCAN
module is available). If a device is programmed as UART/MultiCAN (LIN BSL is not
available), then the entry to the respective BSL (UART or MultiCAN) is decided based
on their initial header frames.
Note: UART BSL is supported only via UART module and not UART1.
Note: For BSL modes, only the default set of receive/transmit pins of UART and
MultiCAN node 0 (P1.0/P1.1) can be used.
Note: For the Flash devices, BSL mode is entered automatically via user mode pin
configuration if no valid password is installed and the data at memory address
