NXENDEC PIN
Power Down
The LAN91C96I can enter power down mode by means of the PWRDWN pin (pin 68) or the PWRDN bit
(Control Register, bit 13). When in power down mode, the LAN91C96I will:
The PWRDWN pin is internally gated with the RESET (RESET pin before de-glitching) and with the
SRESET bit (COR bit 7). This gating function internally negates power down whenever RESET is high or
SRESET is high to allow the oscillator to run during RESET. Except for this gating function, all other uses
of the RESET pin use a de-glitched version of the signal as defined in the pin description section.
