CHAPTER 15 A/D CONVERTER
15.3.3 Example of EI
In pause mode, the EI
• Converts analog input (AN3) 12 times in a certain interval
• Transfer conversion data to the addresses 600
• Activate with external edge input
• Maximum interrupt level

Description of operation
Setting of maximum interrupt, activation of EI
interrupt, and setting of descriptor address.
Destination address of conversion data.
Transfers word data and increments destination address
after transmission. Transfer from I/O to memory.
Terminates by a request from a resource.
Destination address
Transfers data 12 times with EI
Single mode, start channel AN3, end channel AN3 (one-
channel conversion).
Activation with external edge, start of A/D converter.
Recover from interrupt.
