49 / 73 page TRH031M Datasheet www.3ALogics.com | Confidential 49 Chapter8 Interrupt 8.1 Introduction TRH031M supports various types of interrupt. Using interrupt benefits for microprocessor to control TRH031M. First, processing speed enhancement can be expected and second, efficiency in microprocessor calculation. If microprocessor controls more than 2 devices, benefits of interrupt enhance. TRH031M supports total of 6 interrupts and user can select choose to use any interrupt. 8.2 Interrupt Use Method Table 8-1 IEN register Name Address Reset Value IEN 0x06 0x00 7-bit 6-bit 5-bit 4-bit 3-bit 2-bit 1-bit 0-bit SetIEn 0 TimerIEn TxIEn RxIEn IdleIEn HiAlertIEn LoAlertIEn Number Name Description 7 SetIEn 0: Clear Bit. From 0~6, set marked bit as 0. 1: Set Bit. 0~6 set marked bit as 1. 5 TimerIEn 0: Not transfer TimerIRq interrupt signal to IRQ pin 1: Transfer TimerIRq interrupt signal to IRQ pin. 4 TxIEn 0: Not transfer TxIRq interrupt signal to IRQ pin. 1: Transfer TxIRq interrupt signal to IRQ pin. 3 RxIEn 0: Not transfer RxIRq interrupt signal to IRQ pin. 1: Transfer RxIRq interrupt signal to IRQ pin. 2 IdleIEn 0: Not transfer IdleIRq interrupt signal to IRQ pin. 1: Transfer IdleIRq interrupt signal to IRQ pin. 1 HiAlertIEn 0: Not transfer HiAlertIRq signal to IRQ pin. 1: Transfer HiAlertIRq signal to IRQ pin. 0 LoAlertIEn 0: Not transfer LoAlertIRq interrupt signal to IRQ pin. 1: Transfer LoAlertIRq interrupt signal to IRQ pin. |
