Section 4 Modes of Operation
4.1 Overview
Eight possible modes determine the operating configuration of the MC9S12DJ64. Each mode has an
associated default memory map and external bus configuration.
Three low power modes exist for the device.

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 Multiplexed External Bus Interface Block Guide.
