Timer 2 interface module (TIM2) 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
–
$FFCC and $FFCD; TIM2 channel 5
–
$FFCE and $FFCF; TIM2 channel 4
–
$FFD0 and $FFD1; TIM2 channel 3
–
$FFD2 and $FFD3; TIM2 channel 2
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.
10.15 Exiting Stop Mode
These events restart the system clocks and load the program counter with the reset
vector or with an interrupt vector:
External reset — A low on the RST pin resets the MCU and loads the
program counter with the contents of locations $FFFE and $FFFF.
External interrupt — A high-to-low transition on an external interrupt pin
loads the program counter with the contents of locations:
–
$FFFA and $FFFB; IRQ pin
–
$FFE0 and $FFE1; keyboard interrupt pins (low-to-high transition when
KBIPx bits are set)
Low-voltage inhibit (LVI) reset — A power supply voltage below the VTRIPF
voltage resets the MCU and loads the program counter with the contents of
locations $FFFE and $FFFF.
Break interrupt — In emulation mode, a break interrupt loads the program
counter with the contents of locations $FFFC and $FFFD.
