POWER ON RESET
The DS80C310 will hold itself in reset during a power-up until 65,536 clock cycles have elapsed. The
power-on reset used by the DS80C310 differs somewhat from other members of the High-Speed
Microcontroller family. The crystal oscillator may start anywhere between 1.0V and 4.5V but is not
specified. This eliminates the need for an RC reset circuit. For voltage-specific precision brownout
detection, an external component will be needed. When the device goes through a power-on reset, the
POR flag will be set in the WDCON (D8h) register at bit 6.
INTERRUPTS
The DS80C310 provides 10 interrupt sources with two priority levels. Software can assign high or low
priority to all sources. All interrupts that are new to the 8051 have a lower natural priority than the
originals.
