10. DTP (Data Transfer Peripheral) /External Interrupt Circuit
The DTP/external interrupt function detects interrupt requests and data transfer requests input from external
devices and passes these to the CPU as external interrupt requests. This block can also activate the extended
intelligent I/O service (EI
2
OS) .

DTP Function
Input pins
8 channels (INT0 to INT7)
Can be set independently for each channel (each pin) in the detection level setup register
(ELVR) .
“H” level, “L” level,
rising edge, or falling edge input
Interrupts can be enabled or disabled in the DTP/external interrupt enable register (ENIR) .
The DTP/external interrupt request register (EIRR) stores interrupt requests.
