3.2 Settings for Triggers at Preset Positions
3.2.4 Making Settings with the MEM_WR Command
3-14
Command Parameters
The details of MODE/DATA_TYPE are described below.
MODE = 1: Volatile memory, 2: Non-volatile memory (Non-volatile memory can be selected only
for common parameters)
DATA_TYPE = 1: Byte, 2: Short, 3: Long, 4: Not supported
SIZE:
Data size for writing (type specified by DATA_TYPE)
ADDRESS: Initial address for writing
DATA:
Data to be written
Command Warning
The details of CMD_ALM of the MEM_RD/MEM_WR command are described below.
Setting Command Data
Examples of using the MEM_WR command for triggers at preset positions to write the setting
table parameters, saving the settings to non-volatile memory, and initializing related parameters
are given below.
Example of Setting the Output Position for Output Setting 1 to 100,000
ADDRESS = 0xF0050000
MODE/DATA_TYPE = 0x13
SIZE = 0x01
DATA = 100000
