Status bits:
Errors bits are latched in the CAN registers.
(1) Bit CUR is set to 1 when the CAN interface is programmed into “CAN NORMAL” for the first time after V2 turn ON. In order
to clear the bit CUR following procedure must be used: after V2 is ON (SBC in Normal mode and V2 above V2 threshold) the CAN
interface must be set into “CAN sleep”, and then turn back into “CAN NORMAL”.
7.1.4
IOR register
Description.: control of HS1 in normal and standby modes
Control bits:
When HS1 has been turned off because of over temperature, it can be turned on again by setting the appropriate control bit to
“1”. Errors bits are latched in the IOR registers.
Status bits:
7.1.5
WUR register
The local wake-up inputs L0, L1, L2, and L3 can be used in both normal and standby mode as port expander and for waking
up the SBC in sleep or stop mode.
