Section 4 Modes of Operation
4.1 Overview
Eight possible modes determine the operating configuration of the MC9S12DP512. 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 (
Section 4.4 Low Power Modes
).
4.2 Chip Configuration Summary
TheoperatingmodeoutofresetisdeterminedbythestatesoftheMODC,MODB,andMODApinsduring
reset(

pinsarelatchedintothesebitsontherisingedgeoftheresetsignal.TheROMCTLsignalallowsthesetting
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.
For further explanation on the modes refer to the HCS12 Multiplexed External Bus Interface (MEBI)
Block Guide.
