For More Information On This Product,
External reset — A logic 0 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 (IRQ pin) loads the program counter with the contents
of locations: $FFFA and $FFFB; IRQ pin.
Break interrupt — A break interrupt loads the program counter
with the contents of $FFFC and $FFFD.
Computer operating properly module (COP) reset — A timeout of
the COP counter resets the MCU and loads the program counter
with the contents of $FFFE and $FFFF.
Low-voltage inhibit module (LVI) reset — A power supply voltage
below the V
counter with the contents of locations $FFFE and $FFFF.
Clock generator module (CGM) interrupt — A CPU interrupt
request from the phase-locked loop (PLL) loads the program
counter with the contents of $FFF8 and $FFF9.
Keyboard module (KBI) interrupt — A CPU interrupt request from
the KBI module loads the program counter with the contents of
$FFDE and $FFDF.
Timer 1 interface module (TIM1) 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 module (TIM2) interrupt — A CPU interrupt
request from the TIM2 loads the program counter with the
contents of:
