These conditions restart the CPU bus clock and bring the MCU out of
wait mode:
When the MCU exits wait mode, there is no delay before code executes;
however, a delay does occur when exiting stop or halt modes.

An external interrupt signal on the IRQ pin — A high-to-low
transition on the IRQ pin loads the program counter with the
contents of locations $1FFA and $1FFB.
An external interrupt signal on a port A external interrupt pin — If
selected by a mask option, a low-to-high transition on a PA3–PA0
pin loads the program counter with the contents of locations
$1FFA and $1FFB.
A core timer interrupt — A core timer overflow or a real-time
interrupt loads the program counter with the contents of locations
$1FF8 and $1FF9.
A programmable timer interrupt — A programmable timer interrupt
driven by an input capture, output compare, or timer overflow
loads the program counter with the contents of locations $1FF6
and $1FF7.
An SIOP interrupt — An SIOP interrupt driven by the completion
of transmitted or received 8-bit data loads the program counter
with the contents of locations $1FF4 and $1FF5.
An analog subsystem interrupt — An analog subsystem interrupt
driven by a voltage comparison loads the program counter with
the contents of locations $1FF2 and $1FF3.
A COP watchdog reset — A timeout of the COP watchdog resets
the MCU and loads the program counter with the contents of
locations $1FFE and $1FFF. Software can enable real-time
interrupts so that the MCU can periodically exit the wait mode to
reset the COP watchdog.
An external reset — A logic zero on the RESET pin resets the
MCU and loads the program counter with the contents of locations
$1FFE and $1FFF.
