MC9S12DP512 Device Guide V^F01^r.^e23^{escale Semiconductor, Inc.}
The "S12 LRAE" is a generic Load RAM and Execute (LRAE) program which will be programmed into
the flash memory of this device during manufacture. This LRAE program will provide greater
programming flexibility to the end users by allowing the device to be programmed directly using CAN or
SCI after it is assembled on the PCB. Use of the LRAE program is at the discretion of the end user and, if
not required, it must simply be erased prior to flash programming. For more details of the S12 LRAE and
its implementation, please see the S12 LREA Application Note (AN2546/D).
It is planned that most HC9S12 devices manufactured after Q1 of 2004 will be shipped with the S12 LRAE
programmed in the Flash. Exact details of the changeover (i.e. blank to programmed) for each product will
be communicated in advance via GPCN and will be traceable by the customer via datecode marking on
the device.
Please contact Motorola SPS Sales if you have any additional questions.
