CHAPTER 17 DTP/EXTERNAL INTERRUPTS
17.4.2
DTP Function
The DTP/external interrupt has the DTP function that detects the signal of the external
peripheral device from the DTP/external interrupt pin to start the EI
2
OS.
■
DTP Function
The DTP function detects the signal level set by the detection level setting register of the DTP/external
interrupt function to start the EI
2
OS.
•
When the EI
2
OS operation is already enabled (ICR:ISE = 1) at the point when the interrupt request is
accepted by the CPU, the DTP function starts the EI
2
OS and starts data transfer.
•
When transfer of one data item is completed, the descriptor is updated and the DTP/external interrupt
request flag bit is cleared to prepare for the next request from the DTP/external interrupt pin.
•
When the EI
2
OS completes transfer of all the data, control branches to the interrupt processing.
