Selective boot mode
The selective boot is a subcase of the Alternate Boot mode. When none of the signatures
are correct, instead of executing the standard bootstrap loader (triggered by P0L.4 low at
reset), an additional check is made.
Address 00’1FFCh is read again with the following behavior:
●
●
Table 38.
Therefore a value:

2..7
If value is 0000h or FFFFh, a jump is performed to the standard bootstrap loader.
Otherwise:
–
–
0xXX03 configures the Selective Bootstrap Loader to poll for RxD0 and CAN1_RxD.
0xXX01 configures the Selective Bootstrap Loader to poll only RxD0 (no boot via CAN).
0xXX02 configures the Selective Bootstrap Loader to poll only CAN1_RxD (no boot via
UART).
Other values allow the ST10F276Z5 to execute an endless loop into the Test-Flash.
Bit
High byte is disregarded.
Low byte bits select which communication channel is enabled.
Selective boot
UART selection
‘0’: UART is not watched for a Start condition.
‘1’: UART is watched for a Start condition.
CAN1 selection
‘0’: CAN1 is not watched for a Start condition.
‘1’: CAN1 is watched for a Start condition.
Reserved
For upward compatibility, must be programmed to ‘0’
