FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
High-Speed CAN Transceiver Modes
The mode bit (D0) controls the state of the CAN module,
Normal or Sleep modes. Please see
Table 16
. SC0 bit (D1)
defines the slew rate when the CAN module is in Normal
mode, and controls the wake-up option (wake-up enable or
disable) when the CAN module is in Sleep mode. CAN
module modes (Normal and Sleep) are independent of the
SBC modes. Please see
Table 17
.
Error bits are latched in the CAN registers. Bit (1) CUR is
set to 1 when the CAN interface is programmed into CAN
NORMAL for the first time after V2 turn ON. To clear the CUR
bit, follow this procedure:
Turn V2 ON (SBC in Normal mode and V2 above V2
threshold) the CAN interface must be set into CAN Sleep
Return to CAN NORMAL
Input/Output Control Register (IOR)
Table 18
provides data about HS1 control in Normal and
Standby modes, while
Table 19
provides control bit data.
When HS1 is turned OFF due to an over temperature
condition, it can be turned ON again by setting the
appropriate control bit to 1. Error bits are latched in the Input/
Output Registers (IOR). Please see
Table 20
.
