EEPROM 4K
MC9S12DP256 — Revision 1.1
EEPROM 4K
External Pin Descriptions
This module does not have external pins relevant for the user.
Reset Initialization
Out of reset the module is immediately accessible operating in read
mode.
If a reset occurs while any command is in progress that command will be
immediately aborted. The state of the word being programmed or the
sector / block being erased is not guaranteed.
Modes of Operation
Security Modes There are no security modes for the EEPROM.
Low Power Options When the array or the registers are not being accessed clocking to the
register block is shut off to save power. The only exceptions to this are
the flag bits in the ESTAT register which are updated by internal state
machines.
Run Mode No special current saving modes available.
Wait Mode When the MCU enters WAIT mode and any command is active (CCIF =
0) the command will be completed. If enabled, the CCIF interrupt can be
used to waken the MCU out of Wait mode.
Stop Mode No low power options exist for this module in stop mode. If a command
is active (CCIF = 0) when the MCU enters the STOP mode, the
command will be aborted and the and the high voltage circuitry to the
EEPROM array will be switched off.
