⢠External interrupt â 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 â A break interrupt loads the program counter
with the contents of $FFFC and $FFFD.
⢠Computer operating properly module (COP) reset â 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 â A power supply voltage
below the Vtripf voltage resets the MCU and loads the program
counter with the contents of locations $FFFE and $FFFF.
⢠Clock generator module (CGM) interrupt â 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 â A CPU interrupt request from
the KBI module loads the program counter with the contents of
$FFE0 and $FFE1.
⢠Timer 1 interface module (TIM1) interrupt â A CPU interrupt
request from the TIM1 loads the program counter with the
contents of:
â $FFF2 and $FFF3; TIM1 overflow
â $FFF4 and $FFF5; TIM1 channel 1
â $FFF6 and $FFF7; TIM1 channel 0
⢠Timer 2 interface module (TIM2) interrupt â A CPU interrupt
request from the TIM2 loads the program counter with the
contents of:
â $FFEC and $FFED; TIM2 overflow
â $FFEE and $FFEF; TIM2 channel 1
â $FFF0 and $FFF1; TIM2 channel 0
⢠Serial peripheral interface module (SPI) interrupt â A CPU
interrupt request from the SPI loads the program counter with the
contents of:
â $FFE8 and $FFE9; SPI transmitter
â $FFEA and $FFEB; SPI receiver
