ST10 configuration in CAN BSL
When the ST10F276Z5 enters BSL mode via CAN, the configuration shown in
automatically set (values that deviate from the normal reset values are marked in bold).
Table 32.
1. In Bootstrap modes (standard or alternate) ROMEN, bit 10 of SYSCON, is always set regardless of EA pin
2. BUSCON0 is initialized with 0000h, external bus disabled, if pin EA is high during reset. If pin EA is low
Other than after a normal reset, the watchdog timer is disabled, so the bootstrap loading
sequence is not time limited. Pin CAN1_TxD1 is configured as output, so the ST10F276Z5
can return the identification frame. Even if the internal IFLASH is enabled, a code cannot be
executed from it.
Loading the start-up code via CAN
After sending the acknowledge byte, the BSL enters a loop to receive 128 bytes via CAN1.
Hint: The number of bytes loaded when booting via the CAN interface has been extended to
128 bytes to allow the reconfiguration of the CAN Bit Timing Register with the best timings
(synchronization window, ...). This can be achieved by the following sequence of
instructions:
ReconfigureBaud rate:
These 128 bytes are stored sequentially into locations 00’FA40
IRAM, allowing up to 64 instructions to be placed into the RAM area. To execute the loaded
code the BSL then jumps to location 00’FA40
bootstrap loading sequence is now terminated; however, the ST10F276Z5 remains in BSL

level. BYTDIS, bit 9 of SYSCON, is set according to data bus width selection via Port0 configuration.
during reset, BUSACT0, bit 10, and ALECTL0, bit 9, are set enabling the external bus with lengthened ALE
signal. BTYP field, bit 7 and 6, is set according to Port0 configuration.
