Channel Usage
A channel can be specified by CA1, CA2 and CA3. In stand-alone mode, CA1–CA3 pins are used
while in microcontroller interface mode, command data is input with (CA1–CA3).
1. Selection of a channel in direct mode and flex mode
The number of recording words is 8 and is specified by CA1–CA3 as follows:
