The Configuration screen aims to ease the task of configuring the ISD15100. To set the configuration
registers, microcontroller could either send several ‘write config register’ commands or simply issue a
Voice Macro command which consists of a group of ‘write config register’ commands.
In this screen, users can set a path for record or playback and generate automatic configuration bits
that can be ported to the VM editor. Once you set up a path, you can save it by clicking on the ‘Add’
button (A) and assigning a name for the path such as ‘Play from Memory to Speaker’, or ‘REC from
ANAIN’. This is useful when you are editing Voice Macro groups.
There are several default configuration paths; users cannot delete these configurations. The Update
(B) is used to update an existing path (user settings). When selecting a default path by clicking on a
configuration path, you can change the path on the diagram and assign a new name to it.
Please note that the CFG17 bit 0 (Immediately Update, C) and bit 1 (Update, D) are displayed on the
path view as these two bits decide how the configuration registers are updated.

Configuration
Immediately Update:
o
This bit set to one turns off double buffering of configuration. Thus configuration is
updated after each register byte is written. When this bit is set to zero, the
configuration register setting is not made active until a one is written to the ‘Update’
bit.
