12.8.1 MSCAN08 Sleep Mode
The CPU can request the MSCAN08 to enter the low-power mode by asserting the SLPRQ bit in the
module configuration register (see
depends on its activity:
Freescale Semiconductor

•
If it is transmitting, it continues to transmit until there is no more message to be transmitted, and
then goes into sleep mode
If it is receiving, it waits for the end of this message and then goes into sleep mode
If it is neither transmitting or receiving, it will immediately go into sleep mode
1. ‘X’ means don’t care.
The application software must avoid setting up a transmission (by clearing
or more TXE flags) and immediately request sleep mode (by setting
SLPRQ). It then depends on the exact sequence of operations whether
MSCAN08 starts transmitting or goes into sleep mode directly.
