72 / 120 page  MB90330A Series 72 13. DTP/External interrupt circuit DTP (Data Transfer Peripheral)/External interrupt circuit detects the interrupt request input from the external interrupt input terminal (INT7 to INT0) , and outputs the interrupt request. • DTP/External interrupt circuit function The DTP/External interrupt function outputs an interrupt request upon detection of the edge or level signal input to the external interrupt input pins (INT7 to INT0). If CPU accepts the interrupt request, and if the extended intelligent I/O service (EI2OS) is enabled, branches to the interrupt handling routine after completing the automatic data transfer (DTP function) performed by EI2OS. And if EI2OS is disabled, it branches to the interrupt handling routine without activating the automatic data transfer (DTP function) performed by EI2OS. • Overview of DTP/External interrupt circuit External interrupt DTP function Input pin 8 channels (P60/INT0, P61/INT1, P62/INT2/SIN, P63/INT3/SOT, P64/INT4/SCK, P65/INT5/PWC, P66/INT6/SCL0, P67/INT7/SDA0) Interrupt source The detection level or the type of the edge for each terminal can be set in the request level setting register (ELVR). Input of H level/L level/rising edge/falling edge. Interrupt number #18 (12H), #20 (14H), #22 (16H), #24 (18H) Interrupt control Enabling/disabling the interrupt request output using the DTP/interrupt enable register (ENIR) Interrupt flag Holding the interrupt causes using the DTP/interrupt cause register (EIRR) Process setting Disable EI2OS (ICR: ISE=“0”) Enable EI2OS (ICR: ISE=“1”) Process Branched to the interrupt handling routine After an automatic data transfer by EI2OS, branched to the interrupt handling routine |
