Low-Power Modes
Exiting Wait Mode
• Low-voltage inhibit (LVI) module reset — A power supply voltage below the
V_TRIPF voltage resets the MCU and loads the program counter with the
contents of locations $FFFE and $FFFF.
• Clock generator module (CGM) interrupt — A CPU interrupt request from
the ICG loads the program counter with the contents of $FFF8 and $FFF9.
• Keyboard interrupt (KBI) module — A CPU interrupt request from the KBI
module loads the program counter with the contents of $FFE0 and $FFE1.
• Timer 1 interface (TIM1) module interrupt — A CPU interrupt request from
the TIM1 loads the program counter with the contents of:
– $FFF2 and $FFF3; TIM1 overflow
– $FFF4 and $FFF5; TIM1 channel 1
– $FFF6 and $FFF7; TIM1 channel 0
• Timer 2 interface (TIM2) module interrupt — A CPU interrupt request from
the TIM2 loads the program counter with the contents of:
– $FFEC and $FFED; TIM2 overflow
– $FFEE and $FFEF; TIM2 channel 1
– $FFF0 and $FFF1; TIM2 channel 0
• Serial peripheral interface (SPI) module interrupt — A CPU interrupt request
from the SPI loads the program counter with the contents of:
– $FFE8 and $FFE9; SPI transmitter
– $FFEA and $FFEB; SPI receiver
• Serial communications interface (SCI) module interrupt — A CPU interrupt
request from the SCI loads the program counter with the contents of:
– $FFE2 and $FFE3; SCI transmitter
– $FFE4 and $FFE5; SCI receiver
– $FFE6 and $FFE7; SCI receiver error
• Analog-to-digital converter (ADC) module interrupt — A CPU interrupt
request from the ADC loads the program counter with the contents of:
$FFDE and $FFDF; ADC conversion complete.
• Timebase module (TBM) interrupt — A CPU interrupt request from the TBM
loads the program counter with the contents of: $FFDC and $FFDD; TBM
interrupt.
• Motorola scalable controller area network (MSCAN) module interrupt — A
CPU interrupt request from the MSCAN08 loads the program counter with
the contents of:
– $FFD4 and $FFD5; MSCAN08 transmitter
– $FFD6 and $FFD7; MSCAN08 receiver
– $FFD8 and $FFD9; MSCAN08 error
– $FFDA and $FFDB; MSCAN08 wakeup
