7.3.3 Clocks in Wait Mode
7.4 Reset and System Initialization
MC68HC908MR24 — Rev. 4.1
Freescale Semiconductor
In wait mode, the CPU clocks are inactive. The SIM also produces two
sets of clocks for other modules. Refer to the wait mode subsection of
each module to see if the module is active or inactive in wait mode.
Some modules can be programmed to be active in wait mode.
The MCU has these reset sources:
All of these resets produce the vector $FFFE–FFFF ($FEFE–FEFF in
monitor mode) and assert the internal reset signal (IRST). IRST causes
all registers to be returned to their default values and all modules to be
returned to their reset states.
An internal reset clears the SIM counter (see
external reset does not. Each of the resets sets a corresponding bit in
the SIM reset status register (SRSR). See
Register.
