54 / 97 page NuMicro NUC230/240 Datasheet Dec. 30, 2014 Page 54 of 97 Revision 1.01 6.2.6.1 Exception Model and System Interrupt Map The following table lists the exception model supported by NuMicro NUC230/240 series. Software can set four levels of priority on some of these exceptions as well as on all interrupts. The highest user- configurable priority is denoted as “0” and the lowest priority is denoted as “3”. The default priority of all the user- configurable interrupts is “0”. Note that priority “0” is treated as the fourth priority on the system, after three system exceptions “Reset”, “NMI” and “Hard Fault”. Exception Name Vector Number Priority Reset 1 -3 NMI 2 -2 Hard Fault 3 -1 Reserved 4 ~ 10 Reserved SVCall 11 Configurable Reserved 12 ~ 13 Reserved PendSV 14 Configurable SysTick 15 Configurable Interrupt (IRQ0 ~ IRQ31) 16 ~ 47 Configurable Table 6-2 Exception Model Vector Number Interrupt Number (Bit In Interrupt Registers) Interrupt Name Source Module Interrupt Description 1 ~ 15 - - - System exceptions 16 0 BOD_INT Brown-out Brown-out low voltage detected interrupt 17 1 WDT_INT WDT Watchdog Timer interrupt 18 2 EINT0 GPIO External signal interrupt from PB.14 pin 19 3 EINT1 GPIO External signal interrupt from PB.15 pin 20 4 GPAB_INT GPIO External signal interrupt from PA[15:0]/PB[13:0] 21 5 GPCDEF_INT GPIO External interrupt from PC[15:0]/PD[15:0]/PE[15:0]/PF[3:0] 22 6 PWMA_INT PWM0~3 PWM0, PWM1, PWM2 and PWM3 interrupt 23 7 PWMB_INT PWM4~7 PWM4, PWM5, PWM6 and PWM7 interrupt 24 8 TMR0_INT TMR0 Timer 0 interrupt 25 9 TMR1_INT TMR1 Timer 1 interrupt 26 10 TMR2_INT TMR2 Timer 2 interrupt 27 11 TMR3_INT TMR3 Timer 3 interrupt 28 12 UART02_INT UART0/2 UART0 and UART2 interrupt 29 13 UART1_INT UART1 UART1 interrupt 30 14 SPI0_INT SPI0 SPI0 interrupt |
