Section 4 Modes of Operation
4.1 Overview
Eight possible modes determine the operating configuration of the MC9S12K-Family. Each mode has an
associated default memory map and external bus configuration controlled by a further pin.
Three low power modes exist for the device.
4.2 Chip Configuration Summary
The operating mode out of reset is determined by the states of the MODC, MODB, and MODA pins during
reset ((Table 4-1)). 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 mean 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.
For further explanation on the modes refer to the HCS12 MEBI Block Guide.
