Freescale Semiconductor, Inc.
When a dominant level is detected on the MCAN bus, the MCAN is woken up and a wake-up
interrupt is generated.
Under normal operation the two MCAN bus lines are forced to complementary logic levels. The
level of one of the two wires can be disregarded and replaced by V
/2 by setting one of the control
DD
bits, RX0 or RX1.
5.5.1
Sleep comparator reference
When the COMPSEL bit in the MCAN command register ($21) is cleared the sleep comparator
inputs are the same as for the active comparator. However, when the COMPSEL bit is set each
5
input is compared with V
/2 (VDDH – see
Figure
5-6) to detect a dominant level. For further
DD
details of the active comparator, the sleep comparator and VDDH, refer to
Section
12.
