SH1 distinguishes between a power on reset and a manual reset by sampling the state of the NMI input when the RESET line goes high If NMI is high at this point a power on reset sequence is initiated internally and the SH1 is initialised throughout If NMI is low the manual reset sequence initiates the SH1 except the following e bus state controller e pin function controller e IO ports The LCEVB SH1 by default generates a power on reset when e power is applied into the system e reset pushbutton is depressed and released 24 NMI Circuitry The NMI input of the SH1 is an independent edge triggered input NMI may be generated on the positive or negative going transition depending on the setting of the Interrupt Control register ICR NMIE bit The LCEVB SH1 uses two NAND gates U3A and U3B as an inverter to de bounce the output of momentary pushbutton S2 ln the quiescent case the output of U3B and thus the SH1 NMI input is high Closing depressing S2 cause the NMI signal to go low until S2 is released The default value of ICR NMIE is 0 and NMI is generated when NMI goes low Multiple bounces of the switch on the normally open closure will have no further effect switches bounce on the active closure only and the NMI signal will stay low until S2 is released Since the quiescent state of NMI is high closing the reset pushbutton S1 always generates a power on reset In other words when the board is reset all SH1 internal circuitry
