Dear all, I have a problem in MPC5121 sleep mode. As you know MPC5121 use e300c4 core. When I make the e300c4 core into sleep mode, it will return to full power mode when the“decrementer interrupt” occurred.
But in the e300 core reference manual said that the “decrementer interrupt”have no effect when e300 core in sleep mode, because the time base and decrementer are disabled while the core is in sleep mode. Can anybody explain about this procedure ? Another question is how can I disable the“decrementer interrupt”without disable int,smi, or mcpinternal signals. Any help or suggestion would be very helpful. Thank you for your time. -- Best Regards, Li Tao
