Chapter 5
Resets, Interrupts, and General System Control
5.1
This section discusses basic reset and interrupt mechanisms and the various sources of reset and interrupt
in the MC9S08EL32 Series and MC9S08SL16 Series. Some interrupt sources from peripheral modules
are discussed in greater detail within other sections of this data sheet. This section gathers basic
information about all reset and interrupt sources in one place for easy reference. A few reset and interrupt
sources, including the computer operating properly (COP) watchdog are not part of on-chip peripheral
systems with their own chapters.

Reset and interrupt features include:
5.3
Resetting the MCU provides a way to start processing from a known set of initial conditions. During reset,
most control and status registers are forced to initial values and the program counter is loaded from the
reset vector (0xFFFE:0xFFFF). On-chip peripheral modules are disabled and I/O pins are initially
configured as general-purpose high-impedance inputs with pull-up devices disabled. The I bit in the
condition code register (CCR) is set to block maskable interrupts so the user program has a chance to
initialize the stack pointer (SP) and system control settings. SP is forced to 0x00FF at reset.
The MC9S08EL32 Series and MC9S08SL16 Series has eight sources for reset:
Each of these sources, with the exception of the background debug forced reset, has an associated bit in
the system reset status register (SRS).
