STANDBY Mode
The transition from CPU operating mode (NORMAL/SLOW) to STANDBY mode (HALT/STOP) is executed by
the program. CPU wakes up from STANBY mode by the interrupt. Figure:4.2.9 shows the flow diagram of transi-
tion to/from STANDBY mode.
Before the transition to STANDBY mode, the following settings are required:
1. Set the PSW.MIE and xICR.IE to "0" to disable all maskable interrupts.
2. Select the interrupt source to wake up CPU from STANBY mode and set only the corresponding xICR.IE to
"1". Set the PSW.MIE to "1".
3. Set STANBY mode in the CPUM.
