MC68HC908GP20 — Rev 2.1 Advance Information
Freescale Semiconductor 67
• Serial communications interface module (SCI) 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 module (ADC) 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.
3.16 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 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 loads the program counter with the contents of
locations:
– $FFFA and $FFFB; IRQ
pin
– $FFE0 and $FFE1; keyboard interrupt pins
• Low-voltage inhibit (LVI) reset — A power supply voltage below
the LVI
tripf
voltage resets the MCU and loads the program counter
with the contents of locations $FFFE and $FFFF.
• Break interrupt — A break interrupt loads the program counter
with the contents of locations $FFFC and $FFFD.
• Timebase module (TBM) interrupt — A TBM interrupt loads the
program counter with the contents of locations $FFDC and $FFDD
when the timebase counter has rolled over. This allows the TBM
to generate a periodic wakeup from stop mode.
