Accessory Control
The telephone can detect accessories connected to the I/O connector and control the power supply to them. These are
controlled by the signal lines detailed in the following table.
Note that the software needs to set ACC_PWR high before checking DATA_MODE0 and DATA_MODE1.
Any data accessories connected to the Car Kit without a power supply behave as if they were connected directly to the handset.
Input status in this case is as without Car Kit connected.
