Chapter 16 Freescale’s Scalable Controller Area Network (S12MSCANV3)
16.4.5.7
The MSCAN is in disabled mode out of reset (CANE=0). All module clocks are stopped for power saving,
however the register map can still be accessed as specified.
16.4.5.8
The MSCAN can be programmed to wake up from sleep or power down mode as soon as CAN bus activity
is detected (see control bit WUPE in MSCAN Control Register 0 (CANCTL0). The sensitivity to existing
CAN bus action can be modified by applying a low-pass filter function to the RXCAN input line (see
control bit WUPM in
This feature can be used to protect the MSCAN from wake-up due to short glitches on the CAN bus lines.
Such glitches can result from—for example—electromagnetic interference within noisy environments.
16.4.6
The reset state of each individual bit is listed in
the registers and their bit-fields.
16.4.7
This section describes all interrupts originated by the MSCAN. It documents the enable bits and generated
flags. Each interrupt is listed and described separately.
16.4.7.1
The MSCAN supports four interrupt vectors (see
(for details see
Section 16.3.2.8, “MSCAN Transmitter Interrupt Enable Register
Refer to the device overview section to determine the dedicated interrupt vector addresses.
16.4.7.2
At least one of the three transmit buffers is empty (not scheduled) and can be loaded to schedule a message
for transmission. The TXEx flag of the empty message buffer is set.
