3B Op-Code: Write block of memory
Supported By:
Class 2 Interpreter 1
Description:
The 3B Op-Code is used to download data to EEPROM using mode 3B messages. The data that is
downloaded is determined by the information contained in the Action Fields.

AC3:
Exception control action field
00 -
Used to write Configuration / VIN / RSCOSN / … data to a block (AC1)
01 - Used to configure
a Module
using the 3B mode by using data from a calibration file (AC1).
Negative responses will be ignored.
02 - Used to reset (clear) all learned values associated with the data block to initial values as
defined by the controller. The Block Number to reset is indicated by AC1.
03 - Used to write end model part number in binary coded decimal format. Usable option only when
AC1 is 08.
04 - Used to write a routine from the
utility file to a memory block, where AC2 is the routine number
and AC1 is the block number.
05 - Used to configure a Module using the 3B mode by using data from a calibration file (AC1) that
includes header
information within the file
. The header
information will be skipped
– 12 bytes.
Negative responses will be ignored.
06 - Used to configure a Module using the 3B mode by using data from a calibration file (AC1).
A negative response will be processed and will halt the configuration data writing.
07 - Used to configure a Module using the 3B mode by using data from a calibration file (AC1) that
includes header information within the file
. The header information will be skipped
– 12 bytes.
A negative response will be processed and will halt the configuration data writing.
08
– Used to write data from a 256-byte internal storage buffer (AC2) to the block number identified
in AC1.
