as the ST6265. NMI There is no external NMI pin in the ST6294. Although the ST6294 uses the standard ST62 core, which includes the NMI function. The user program therefore cannot place the ST62 in NMI mode. However, NMI mode is the default mode at power on or after a system reset generated by the watchdog or through the RESET pin. In these cases, the user software must perform a RETI instruction to exit from NMI mode to enable further interrupts from other sources prior to any other instruction.
