32 / 159 page  Analog Integrated Circuit Device Data Freescale Semiconductor 32 MC34708 Functional Block Description 7.4.2 Interrupt Bit Summary Table 21 summarizes all interrupt, mask, and sense bits associated with INT control. For more detailed behavioral descriptions, refer to the related chapters. Table 21. Interrupt, Mask and Sense Bits Interrupt Mask Sense Purpose Trigger Debounce Time ADCDONEI ADCDONEM - ADC has finished requested conversions L2H 0 TSDONEI TSDONEM - Touch screen has finished conversion L2H 0 TSPENDET TSPENDETM - Touch screen pen detect Dual 1.0 ms USBOVP USBOVPM USBOVPS VBUS over-voltage Sense is 1 if above threshold. Dual Programmable SUP_OVP_DB LOWBATT LOWBATTM - Low battery detect Sense is 1 if below LOWBAT threshold H2L Programmable VBATTDB USBDET USBDETM USBDETS USB VBUS detect Sense is 1 if detected Dual Programmable VBUSDB Stuck_Key_RCV Stuck_Key_RCV_m - Stuck key has recovered L2H Stuck_Key Stuck_Key_m - Stuck key detected L2H ADC_Change ADC_Change_m ADC_STATUS ADC result changed Sense is 1 if conversion is completed, 0 if in progress L2H Unknown_Atta Unknown_Atta_m - Unknown accessory detected L2H LKR LKR_m - Remote control long key is released L2H LKP LKP_m - Remote control long key is pressed L2H KP KP_m - Remote control key is pressed L2H Detach Detach_m - Accessory detached L2H Attach Attach_m - Accessory attached L2H ID_GNDS Sense is 1 if ID pin is grounded ID_FLOATS Sense is 1 if ID pin is floating ID_DET_ENDS Sense is 1 if ID resistance detection is complete VBUS_DET_ENDS Sense is 1 if VBUS PTSI is complete SCPI SCPM - Regulator short-circuit protection tripped L2H min. 4.0 ms max 8.0 ms 1HZI 1HZM - 1.0 Hz time tick L2H 0 TODAI TODAM - Time of day alarm L2H 0 PWRON1I PWRON1M PWRON1S Power on button 1 event Sense is 1 if PWRON1 is high H2L 30 ms (36) L2H 30 ms PWRON2I PWRON2M PWRON2S Power on button 2 event Sense is 1 if PWRON2 is high H2L 30 ms (36) L2H 30 ms SYSRSTI SYSRSTM - System reset through PWRONx pins L2H 0 WDIRESETI WDIRESETM - WDI silent system restart L2H 0 PCI PCM - Power cut event L2H 0 |
