1.3
The clock and reset generator provides the internal clock signals for the core and all peripheral modules.
Figure 1-5
chapter for details on clock generation.
1.4
There are eight possible modes of operation available on the MC9S12NE64. Each mode has an associated
default memory map and external bus configuration.
1.4.1
The operating mode out of reset is determined by the states of the MODC, MODB, and MODA pins during
reset. The MODC, MODB, and MODA bits in the MODE register show the current operating mode and
provide limited mode switching during operation. The states of the MODC, MODB, and MODA pins are
latched into these bits on the rising edge of the RESET signal. The ROMCTL signal allows the setting of
the ROMON bit in the MISC register thus controlling whether the internal FLASH is visible in the memory
map. ROMON = 1 means the FLASH is visible in the memory map. The state of the ROMCTL pin is
latched into the ROMON bit in the MISC register on the rising edge of the RESET signal.
