Consult the TIM_16B8C Block User Guide for information about the Standard Timer module. When the
TIM_16B8C Block User Guide refers to freeze mode this is equivalent to active BDM mode.
Section 11 Analog to Digital Converter (ATD) Block
Description
Consult the ATD_10B16C Block User Guide for information about the Analog to Digital Converter
module. When the ATD_10B16C Block User Guide refers to freeze mode this is equivalent to active BDM
mode. The ETRIG pin option is not available, but the external trigger feature is available on ATD channels.
NOTE: In QFP80 package ATDIEN0 should be set always to $00.
Section 12 Inter-IC Bus (IIC) Block Description
Consult the IIC Block User Guide for information about the Inter-IC Bus module.
Section 13 Serial Communications Interface (SCI) Block
Description
There are two Serial Communications Interfaces (SCI1 and SCI0) implemented on the MC9S12B128
device. Consult the SCI Block User Guide for information about each Serial Communications Interface
module.

Consult the SPI Block User Guide for information about the Serial Peripheral Interface module.
Section 15 Flash EEPROM 128K1 Block Description
Consult the FTS128K1 Block User Guide for information about the flash module.
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).
